ksmbd: use u8 for SMB2 oplock level values
The SMB2 oplock level is an unsigned 8-bit wire value, but
smb20_oplock_break_ack() stores it in a plain char. On architectures where
plain char is signed, the value 0xff becomes -1 and cannot compare equal to
SMB2_OPLOCK_LEVEL_LEASE (0xff). The acknowledgment is consequently rejected
with STATUS_INVALID_OPLOCK_PROTOCOL instead of the intended
STATUS_INVALID_PARAMETER.
Use u8 for the request and response oplock-level variables. This preserves
all wire values in their original representation.
