perf report: Enable finding kernel inline functions

Currently perf supports a mode to query inline stack. It works well for
finding user space inline functions but it doesn't work for kernel ones,
due to some unnecessary check.

This patch removes these unnecessary checks. Now kernel inline functions
can be reported.

For example:

  perf report --inline -g func --stdio

  |--46.19%--do_huge_pmd_anonymous_page
  |          do_huge_pmd_anonymous_page (inline)
  |          __do_huge_pmd_anonymous_page (inline)
  |          __SetPageUptodate (inline)
  |          __set_bit (inline)

  The result is compared with the output of addr2line. They match.
