dm: raid fix write_mostly arg validation
Fix off-by-one error in validation of write_mostly. The user-supplied value given for the 'write_mostly' argument must be an index starting at 0. The validation of the supplied argument failed to check for 'N' ('>' vs '>='), which would have caused an access beyond the end of the array.
