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.

In gcm_mode_decrypt_contiguous_blocks(), if vmem_alloc() fails,
bcopy is called with a NULL pointer destination and a length > 0.
This results in undefined behavior. Further ctx->gcm_pt_buf is
freed but not set to NULL, leading to a potential write after
free and a double free due to missing return value handling in
crypto_update_uio(). The code as is may write to ctx->gcm_pt_buf
in gcm_decrypt_final() and may free ctx->gcm_pt_buf again in
aes_decrypt_atomic().
The fix is to slightly rework error handling and check the return
