ath: dfs_pattern_detector: Fix possible null-pointer dereference in channel_detector_create()
[ Upstream commit 4b6012a7830b813799a7faf40daa02a837e0fd5b ]
kzalloc() is used to allocate memory for cd->detectors, and if it fails,
channel_detector_exit() behind the label fail will be called:
channel_detector_exit(dpd, cd);
In channel_detector_exit(), cd->detectors is dereferenced through:
struct pri_detector *de = cd->detectors[i];
To fix this possible null-pointer dereference, check cd->detectors before
the for loop to dereference cd->detectors.
