qcacld 3.0: Fix return type of few "cdf_atomic" APIs

Propagation from qcacld 2.0 to qcacld 3.0

The atomic variables are of integer type but "cdf_atomic_read",
"cdf_atomic_dec_and_test" and "cdf_atomic_inc_return" APIs
have return type of unsigned int. Because of this, these APIs
return positive value even when it is negative.

This fix change the return value of "cdf_atomic_read",
"cdf_atomic_dec_and_test" and "cdf_atomic_inc_return" APIs
from unsigned int to int so that negative value remains negative.
