xfs: consolidate btree block freeing tracepoints
Don't waste memory on extra per-btree block freeing tracepoints when we
can do it from the generic btree code.
With this patch applied, two tracepoints are collapsed into one
tracepoint, with the following effects on objdump -hx xfs.ko output:
Before:
10 __tracepoints_ptrs 00000b3c 0000000000000000 0000000000000000 00140eb0 2**2
14 __tracepoints_strings 00005453 0000000000000000 0000000000000000 00168540 2**5
29 __tracepoints 00010d90 0000000000000000 0000000000000000 0023f5e0 2**5
After:
10 __tracepoints_ptrs 00000b38 0000000000000000 0000000000000000 001412f0 2**2
14 __tracepoints_strings 00005433 0000000000000000 0000000000000000 001689a0 2**5
29 __tracepoints 00010d30 0000000000000000 0000000000000000 0023fe00 2**5
Column 3 is the section size in bytes; removing these two tracepoints
reduces the size of the ELF segments by 132 bytes.
