[PATCH 4/4] staging: wlan-ng: use GENMASK macro in two bitwise operations in prism2sta.c

[Sergio Paracuellos]

This patch replace actual mask stuff using BIT macros with 
or operators to make use of GENMASK macro which simplifies 
code clearity and readibility.

It applies for two bitwise operations included in prism2sta.c source file.
