[SCSI] mpt: modify mptctl_exit() to call proper deregister functions
This patch fixes some issues of mptctl_exit().
1) It doesn't call mpt_deregister() for mptctl_taskmgmt_id
=> Insmoding/rmmoding mptctl.ko repeadtedly (up to
MPT_MAX_PROTOCOL_DRIVERS-1 at most) can eat up all cb_idx,
and that would cause a lack of MptCallbacks[], MptDriverClass[],
and MptEvHandlers[].
2) It doesn't call mpt_event_deregister() for mptctl_id
=> Need to call it.
3) It calls mpt_reset_deregister() for mptctl_taskmgmt_id
=> This could accidentally deregister an innocent reset handler
that you don't want to.
This patch also adds a check for mptctl_taskmgmt_id.
