[PATCH 28/61] staging: rtl8723bs: inline single-use _clear_cam_entry helper

[Arsenii Pashchenko <ulijg308@gmail.com>]

Remove the _clear_cam_entry() helper function since it has only a
single call site across the driver.

Inline its logic directly into the sole invocation site and modernize
the array declarations. Replace the verbose 'unsigned char' types with
the standard kernel 'u8' type, and swap the explicit hexadecimal zero
sequences for clean, fixed-size bounds with zero-initializers ({0}).

This eliminates an unnecessary abstraction layer, reduces visual noise,
and cleans up the driver's CAM management path.
