Subject: [PATCH 5.15 124/196] smb3: fix snapshot mount option

From: Steve French <stfrench@...rosoft.com>

commit 9405b5f8b20c2bfa6523a555279a0379640dc136 upstream.

The conversion to the new API broke the snapshot mount option
due to 32 vs. 64 bit type mismatch

Fixes: 24e0a1eff9e2 ("cifs: switch to new mount api")
Cc: stable@...r.kernel.org # 5.11+
