qcacld-3.0: Remove QDF_BUG of qdf_spin_is_locked

spin_is_locked() provided by kernel has statement that we should not
rely heavily on the return value, it only tells that the spinlock is
seen to be locked, not that it is locked on your CPU.
Further, on CONFIG_SMP=n builds with CONFIG_DEBUG_SPINLOCK=n, the
return value is always 0.

So we should not use QDF_BUG to test/assert its return value, only be
used for debugging purpose.
