Modify interrupt service routines for INTx, MSI, and MSI-x to support
multiqueue. Modify parameter list of fnic_wq_copy_cmpl_handler to take
cq_index. Modify fnic_cleanup function to use the new function call of
fnic_wq_copy_cmpl_handler. Refactor code to set interrupt mode to MSI-x to
a new function. Add a new stat for intx_dummy.

When calling debugfs functions, there is no need to ever check the return
value. The function can work or not, but the code logic should never do
something different based on this.

This change is to add fnic stats for the max number of CQs (corresponding
to copy WQ) processed in a given interrupt, max time taken by the ISR.

struct timespec is deprecated since it overflows in 2038 on 32-bit
architectures, so we should use timespec64 consistently.
I'm slightly adapting the format strings here, to make sure we print the
nanoseconds with the correct number of leading zeroes.

Added the timestamps for
1. current timestamp
2. last fnic stats read timestamp
3. last fnic stats reset timestamp
and the deltas since last stats read and last reset in fnic stats.
fnic stats uses debugfs

The IO and Abort latency counter counts the time taken to complete the
IO and abort command into broad buckets. This is not intended for
performance measurement, just a debug statistic. current_max_io_time
tries to keep track of the maximum time an IO has taken to complete if
it is > 30sec.

This feature gathers active and cumulative per fnic stats for io,
abort, terminate, reset, vlan discovery path and it also includes
various important stats for debugging issues. It also provided
debugfs and ioctl interface for user to retrieve these stats.
It also provides functionality to reset cumulative stats through
user interface.
