[PATCH v3] platform/x86: hp-bioscfg: remove dead bounds check in audit_log_entries_show

[Muhammad Bilal]

audit_log_entries_show() checks "count * LOG_ENTRY_SIZE > PAGE_SIZE"
prior to entering the loop. Because "count" is already bounded to fit
within PAGE_SIZE, the inner loop check "(LOG_ENTRY_SIZE * i) > PAGE_SIZE"
can never be reached and is dead code.

Remove the redundant inner bounds check and eliminate the unnecessary
"else" block after "break" to clean up the loop control flow.

Resending v3 2/2 unchanged: the previous attempt reached the list with
a corrupted hunk (header/diffstat didn't match the body), which is
what "patch: **** malformed patch at line 65" was. No content change
from the previous v3, this is a clean re-generation of the same diff.

Changes in v3:
  - Remove the dead inner loop check completely instead of adjusting
    the boundary arithmetic, as noted by Ilpo Järvinen.
  - Remove the redundant else block after break.

Changes in v2:
  - None for this patch; resubmitted as part of the v2 series.
