scsi: qla2xxx: Fix serialization of DCBX TLV data request

Browse source

Commit b6faaaf796 ("scsi: qla2xxx: Serialize mailbox request") serialized
mailbox requests from userspace using the 'optrom' mutex. However, in the
case of DCBX TLV data, if the memory for it is already allocated, then the
mailbox request ends up not being serialized because it is done without
holding the 'optrom' mutex.
