qcacmn: Do not update ch_params if RCAC frequency is NULL

Browse Source 
While selecting the next channel after radar, if RCAC is enabled,
RCAC frequency and ch params are chosen. But in case where no
RCAC frequency was found, ch params were filled with 0s which are
then used by the next channel selection logic (random channel)
to figure out the next channel.

Since the ch params were now 0s, the ch width is pointing to
20MHz (0 enum) which results in a 20MHz channel picked irrespective
of current mode.

Do not modify ch params if the RCAC frequency is NULL.
