[PATCH] staging: rtl8723bs: remove unused monitor interface name

[Amirhossein Hajimohammadi]

From: AmirHossein HajiMohammadi <info@xxxxxxxxxxxxxxxxx>

ifname_mon is assigned when the monitor interface is created and cleared
when it is deleted, but the value is never read.

Remove the unused field and its dead stores.
