wifi: wcn36xx: fix channel survey memory allocation size
KASAN reported a memory allocation issue in wcn->chan_survey
due to incorrect size calculation.
This commit uses kcalloc to allocate memory for wcn->chan_survey,
ensuring proper initialization and preventing the use of uninitialized
values when there are no frames on the channel.
