megaraid: Fix possible NULL pointer deference in mraid_mm_ioctl
This adds the needed check after the call to the function mraid_mm_alloc_kioc in order to make sure that this function has not returned NULL and therefore makes sure we do not deference a NULL pointer if one is returned by mraid_mm_alloc_kioc. Further more add needed comments explaining that this function call can return NULL if the list head is empty for the pointer passed in order to allow furture users to understand this required pointer check.
