[SCSI] megaraid: fix compiler warnings 

The user ioctl mailbox can only support a 32 bit address for the
commands structure.  This is fine, since the area it's pointing to is
allocated with pci_alloc_consistent(), so it should be physically <
4GB.  Thus kill the ptr to u32 conversion warnings on 64 bit.
