Subject: [PATCH] perf string: Remove unused macro K()

Unused macro reported by [-Wunused-macros].

This macro is introduced to calculate the 'unit' size, in:

  d2fb8b4151a92223 ("perf tools: Add new perf_atoll() function to parse string representing size in bytes")

  8ba7f6c2faada3ad ("saner perf_atoll()")

This commit has simplified the perf_atoll() function and remove the
'unit' variable. This macro is not deleted, but nowhere else is using
it.

A single letter macro is confusing and easy to be misused.  So remove it
for code cleaning.
