The return value of the ksmbd_vfs_getcasexattr() is long.
However, the return value is being assigned to an unsignef
long variable 'v_len',so making 'v_len' to long. Also, when
comparing to zero in the following code, no type conversion
is required.
silence the warning:
./fs/smb/server/vfs.c:WARNING: Unsigned expression compared
with zero: v_len > 0
