Attila Fülöp 3ac34ca375 ICP: Fix out of bounds write 
If gcm_mode_encrypt_contiguous_blocks() is called more than once
in succession, with the accumulated lengths being less than
blocksize, ctx->copy_to will be incorrectly advanced. Later, if
out is NULL, the bcopy at line 114 will overflow
ctx->gcm_copy_to since ctx->gcm_remainder_len is larger than the
ctx->gcm_copy_to buffer can hold.

The fix is to set ctx->copy_to only if it's not already set.

For ZoL the issue may be academic, since in all my testing I wasn't
able to hit neither of both conditions needed to trigger it, but
other consumers can easily do so.
