[SCSI] megaraid_{mm,mbox}: fix a bug in reset handler
When abort failed, the driver gets reset handleer called. In the reset
handler, driver calls 'scsi_done()' callback for same SCSI command packet
(struct scsi_cmnd) multiple times if there are multiple SCSI command packet
in the pend_list. More over, if there are entry in the pend_lsit with
IOCTL packet associated, the driver returns it to wrong free_list so that,
in turn, the driver could end up with 'NULL pointer dereference..' during
I/O command building with incorrect resource.
Also, the patch contains several minor/cosmetic changes besides this.
