scsi: megaraid_sas: Fix the search of first memory bar
The 2nd parameter of 'find_first_bit' is the number of bits to search. In this case, we are passing 'sizeof(unsigned long)' which is likely to be 4. It is likely that the number of bits in a long was expected here, so use BITS_PER_LONG instead.
