From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently the error return path when 'limits' fails to allocate
does not free the memory allocated for 'combinations'. Fix this
by adding a kfree before returning.
Addresses-Coverity: ("Resource leak")
Fixes: 2626c269702e ("ath11k: add interface_modes to hw_params")
