qcacld-3.0: Report scan info for total NUM_CHANNELS to upper layer

Host allows scan for any channels allowed in the 2 GHz band or
channels allowed in the 5 GHz band or channels allowed in the 6 GHz
band. So the total number of frequencies allowed for the scan is
MAX_CHANNEL (NUM_CHANNELS - 1) defined in enum channel_enum.

Currently on receiving WMI_CHAN_INFO_EVENTID per channel, host
updates the channel info buffer for SIR_MAX_NUM_CHANNELS(64) only.
This result host fails to send channel info for frequencies present
at index MAX_CHANNEL - SIR_MAX_NUM_CHANNELS.

The fix is to allow the host to fill the channel info buffer till
the max allowed (MAX_CHANNEL) channel index.
