LU-10185 gnilnd: Change gnc_tx_bits to unsigned long

gnc_tx_bits declared as __u8. Change to unsigned long.

The goal is to align gnc_tx_bits[] to a 32 bit boundary.
The initial declaration I believe was not a good choice.
The use of the gnc_tx_bits makes more sense as a long than as a 8 bit
value.
It is used by:
static inline int test_and_clear_bit(int nr, unsigned long *addr);
unsigned long find_next_zero_bit(unsigned long *addr, unsigned long
size, unsigned long offset);
static inline int test_and_set_bit(int nr, unsigned long *addr);
all of which takes a unsigned long pointer.

Test-parameters: trivial
