From: Colin Ian King <colin.king@canonical.com>

Currently there are two ndr_read_int64 calls where ret is being checked
for failure but ret is not being assigned a return value from the call.
Static analyis is reporting the checks on ret as dead code.  Fix this.

Addresses-Coverity: ("Logical dead code")
Fixes: 303fff2b8c77 ("ksmbd: add validation for ndr read/write functions")
