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.
