ath: dfs_pattern_detector: Avoid open coded arithmetic in memory allocation
kmalloc_array()/kcalloc() should be used to avoid potential overflow when
a multiplication is needed to compute the size of the requested memory.
kmalloc_array() can be used here instead of kcalloc() because the array is
fully initialized in the next 'for' loop.
Finally, 'cd->detectors' is defined as 'struct pri_detector **detectors;'.
So 'cd->detectors' and '*cd->detectors' are both some pointer.
So use a more logical 'sizeof(*cd->detectors)'.
