Subject: [PATCH v2 2/4] staging: rtl8188eu: remove constant variable and dead code

g_wifi_on is always true. Remove the variable and the code that would
be run only if g_wifi_on was false.

While at it, remove a pointlesss comment that starts with /** and is
misinterpreted as a kernel-doc comment.

v2:
 - fix compiler warning, remove a comment that looks like kernel-doc
