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

[Wang YanQing]

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.

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