Commit 515ce733e8 ("staging:r8188eu: Use lib80211 to encrypt (CCMP) tx frames")
was reverted because it caused scheduling while atomic bugs and hard
freezes. Experimentation showed that there were no freezes and no BUG
messages logged when lib80211_get_crypto_ops() was called directly
rather than indirectly through try_then_request_module().

Reapply "staging:r8188eu: Use lib80211 to encrypt (CCMP) tx frames"
with resolved revert conflicts and replace try_then_request_module()
with direct call to lib80211_get_crypto_ops().

Original commit message:
Put data to skb, decrypt with lib80211_crypt_ccmp, and place back to tx buffer.
