[PATCH] scsi: hpsa: Use min helper for comparison and assignment

[Deepak R Varma]

Simplify code by using min_t() helper macro for logical evaluation
and value assignment. Use the _t variant macro since the variable
types are not same.
Proposed change is identified using minmax.cocci semantic patch script.
