Subject: [PATCH V3] wireless: rtlwifi: Replace variable with a break

This patch removes the variable continual, and change the while loop
to break when efuse_data == 0xFF.

Tested by compilation only.

Changes from V2:
 - Fix typo in the subject
 - Fix indentation

Changes from V1:
 - Fix the indetation
 - Remove remaining } from removed else

Please ignore the patch:
[PATCH 12/19] wireless: Change variable type to bool

And apply this one instead.

The variable continual was declared as int, but was used as bool. I
sent previous patch changing the variable type to bool, but Joe Perches
proposed that removing the variable and adding a break would be better.
