[PATCH] include/asm-generic/atomic.h: use 'unsigned int' instead of 'unsigned long' for atomic_clear_mask()

[Chen Gang]

For atomic_clear_mask(), 'v->counter' is 'int', so it is better to use
'unsigned int' instead of 'unsigned long' for parameter 'mask' to make
atomic_clear_mask() itself consistency.

And atomic_[set/clear]_mask() are pairs, the modification can also let
them consistent with each other.

Although the original implementation can not cause bugs, it is still
better to let it improved.
