staging: rtl8188eu: Fix module loading from tasklet for CCMP encryption
commit 84cad97a717f5749a0236abd5ce68da582ea074f upstream. Commit 6bd082af ("staging:r8188eu: use lib80211 CCMP decrypt") causes scheduling while atomic bugs followed by a hard freeze whenever the driver tries to connect to a CCMP-encrypted network. Experimentation showed that the freezes were eliminated when module lib80211 was preloaded, which can be forced by calling lib80211_get_crypto_ops() directly rather than indirectly through try_then_request_module(). With this change, no BUG messages are logged.
