net: spider_net: Use non-atomic bitmap API when applicable
No concurrent access is possible when a bitmap is local to a function.
So prefer the non-atomic functions to save a few cycles.
- replace a 'for' loop by an equivalent non-atomic 'bitmap_fill()' call
- use '__set_bit()'
While at it, clear the 'bitmask' bitmap only when needed.
