mISDN: improve bitops usage
This improves bitops usages in several points:
- Convert u64 to a proper bitmap declaration. This enables to remove
superfluous typecasting from 'u64' to 'unsigned long *'.
- Convert superfluous atomic bitops to non atomic bitops. The bitmap
is allocated on the stack and it is not accessed by any other threads,
so using atomic bitops is not necessary.
- Use find_next_zero_bit and find_next_zero_bit instead of calling
test_bit() for each bit.
