[PATCH v2] rtlwifi: Fix logic error in enter/exit power-save mode

In commit a269913c52ad ("rtlwifi: Rework rtl_lps_leave() and
rtl_lps_enter() to use work queue"), the tests for enter/exit
power-save mode were inverted. With this change applied, the
wifi connection becomes much more stable.

 Hi, Larry!

 Because commit a269913c52ad is the first commit bring this problem, 
 so maybe use above commit message is ok, right? And stable kernels
 3.10-3.18 don't have commit fd09ff958777, but have a269913c52ad.

 Thanks for suggestion concerning to good subject and commit message
 writing, it is harder than coding sometimes:)

 Changes:
 v1-v2:
 1: Fix subject and commit message.
