sunrpc: fix null pointer dereference on zero-length checksum
commit 6df164e29bd4e6505c5a2e0e5f1e1f6957a16a42 upstream.
In xdr_stream_decode_opaque_auth(), zero-length checksum.len causes
checksum.data to be set to NULL. This triggers a NPD when accessing
checksum.data in gss_krb5_verify_mic_v2(). This patch ensures that
the value of checksum.len is not less than XDR_UNIT.
Fixes: 0653028e8f1c ("SUNRPC: Convert gss_verify_header() to use xdr_stream")
