[PATCH] staging/rtl8723bs: remove unused variable warning

[Meeri Kallio]

This is my first contribution to the Linux kernel. I am a beginner, and I 
would greatly appreciate any feedback you can provide.

This patch removes an unused variable in the rtl8723bs staging driver to silence a compiler warning.
This is a small change, but it's my first step in contributing to the kernel. I look forward to learning and improving from any suggestions.
