Commit 2b2ea09e74a5 ("staging:r8188eu: Use lib80211 to decrypt WEP-frames") causes scheduling while atomic bugs followed by a hard freeze whenever the driver tries to connect to a WEP-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.
