ksmbd: Fix unsigned expression compared with zero

[ Upstream commit 0266a2f791294e0b4ba36f4a1d89b8615ea3cac0 ]

The return value of the ksmbd_vfs_getcasexattr() is signed.
However, the return value is being assigned to an unsigned
variable and subsequently recasted, causing warnings. Use
a signed type.
