qcacld-3.0: Update correct band capability to OEM

In case of lowi, Supported bands are populated from
psoc->soc_nif.user_config.band_capability which is same as
that of ini file and not the intersected band support. In
function wifi_pos_populate_caps caps->supported_bands is
populated from psoc->soc_nif.user_config.band_capability
which may not be supported by firmware.

Fix is to update psoc->soc_nif.user_config.band_capability
with the intersected immediately after fetching intersected
band support to avoid incompatibilty.
