crypto: af_alg - Set merge to zero early in af_alg_sendmsg
[ Upstream commit 9574b2330dbd2b5459b74d3b5e9619d39299fc6f ]
If an error causes af_alg_sendmsg to abort, ctx->merge may contain
a garbage value from the previous loop. This may then trigger a
crash on the next entry into af_alg_sendmsg when it attempts to do
a merge that can't be done.
Fix this by setting ctx->merge to zero near the start of the loop.
Fixes: 8ff590903d5 ("crypto: algif_skcipher - User-space interface for skcipher operations")
