From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
A previous fix added a jump to after_open which now leaves variable
rc in a uninitialized state. A couple of the cases in the following
switch statement do not set variable rc, hence the error check on rc
at the end of the switch statement is reading a garbage value in rc
for those specific cases. Fix this by initializing rc to zero before
the switch statement.
Fixes: 955a9c5b39379 ("cifs: create a helper to find a writeable handle by path name")
Addresses-Coverity: ("Uninitialized scalar variable")
