net: mac802154: Fix general protection fault ...
commit 1165affd484889d4986cf3b724318935a0b120d8 upstream.
syzbot found general protection fault in crypto_destroy_tfm()[1].
It was caused by wrong clean up loop in llsec_key_alloc().
If one of the tfm array members is in IS_ERR() range it will
cause general protection fault in clean up function [1].
Call Trace:
