qcacld-3.0: Fix the size of array ch_list in sme_set_plm_request

Currently the size of array ch_list in sme_set_plm_request is
defined as WNI_CFG_VALID_CHANNEL_LIST and this is incorrect.
This is just an index to the corresponding CFG item. Fix the
size to WNI_CFG_VALID_CHANNEL_LIST_LEN which is the maximum
size that can be passed from the source buffer.
