crypto: sha256_ssse3 - fix stack corruption with SSSE3 and AVX implementations
The _XFER stack element size was set too small, 8 bytes, when it needs to be 16 bytes. As _XFER is the last stack element used by these implementations, the 16 byte stores with 'movdqa' corrupt the stack where the value of register %r12 is temporarily stored. As these implementations align the stack pointer to 16 bytes, this corruption did not happen every time. Patch corrects this issue.
