Mark Johnston 564b6aa7fc aesni: Avoid a potential out-of-bounds load in aes_encrypt_icm()
Given a partial block at the end of a payload, aes_encrypt_icm() would
perform a 16-byte load of the residual into a temporary variable.  This
is unsafe in principle since the full block may cross a page boundary.
Fix the problem by copying the residual into a stack buffer first.
