[PATCH -next 5/5] perf: Remove unused macro K

[Chen Zhongjin]

Unused macro reported by [-Wunused-macros].

This macro is introduced to calculate the 'unit' size, in:
'd2fb8b4151a9 ("perf tools: Add new perf_atoll() function to parse string representing size in bytes")'

'8ba7f6c2faad ("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.
