Remove casting the values returned by memory allocation function.

Coccinelle emits WARNING:

./drivers/message/fusion/mptfc.c:766:17-30: WARNING: casting value returned by memory allocation function to (FCPortPage0_t *) is useless.
./drivers/message/fusion/mptfc.c:907:17-30: WARNING: casting value returned by memory allocation function to (FCPortPage1_t *) is useless.
