scsi: smartpqi: Remove contention for raid_bypass_cnt

Browse source

Reduce CPU contention when incrementing variable raid_bypass_cnt.

Remove the atomic operations for this variable by changing the atomic to an
unsigned int and replace atomic operations with standard operations. The
value is only checked that it is increasing and accuracy is not required.
