arch_topology: Remove early cacheinfo error message if -ENOENT
fetch_cache_info() tries to get the number of cache leaves/levels
for each CPU in order to pre-allocate memory for cacheinfo struct.
Allocating this memory later triggers a:
'BUG: sleeping function called from invalid context'
in PREEMPT_RT kernels.
If there is no cache related information available in DT or ACPI,
fetch_cache_info() fails and an error message is printed:
'Early cacheinfo failed, ret = ...'
Not having cache information should be a valid configuration.
Remove the error message if fetch_cache_info() fails with -ENOENT.
