[PATCH 34/61] staging: rtl8723bs: replace rtw_get_beacon_interval_from_ie with define

[Arsenii Pashchenko <ulijg308@gmail.com>]

Remove the redundant rtw_get_beacon_interval_from_ie() helper function
and introduce a macro definition for the beacon interval offset.

The original function performed a trivial pointer addition (ie + 8).
Replacing it with a descriptive macro eliminates a useless function call
layer while keeping the code self-documenting and free of magic numbers.

Define RTW_BEACON_INTERVAL_IE_OFFSET in the header, clean up the function
definition, and update all call sites to use direct pointer arithmetic.
