scsi: mptctl: Remove unneeded cast from memory allocation

Remove casting the values returned by memory allocation function.

Coccinelle emits WARNING:

./drivers/message/fusion/mptctl.c:2596:14-31: WARNING: casting value returned by memory allocation function to (SCSIDevicePage0_t *) is useless.
./drivers/message/fusion/mptctl.c:2660:15-32: WARNING: casting value returned by memory allocation function to (SCSIDevicePage3_t *) is useless.
