qcacld-3.0: Driver loading failure during monitor mode bring up

Browse source 
The API hdd_update_tgt_cfg decides whether to create a new PDEV
or use the existing one. In this case, the driver is
de-initialized/re-initialized followed by the cfg download. The
FW then generates SYS_READY and the control comes to this function.
Since there is no check for monitor mode the second PDEV is created.
FW seems to provide phy_id = 0 and expects the host to use the
corresponding pdev_id at various places during initialization.
Now here phy_id = 0 and pdev_id = 1, thus initializations fails.

To resolve this issue add a check for monitor mode in hdd_update_tgt_cfg
function and use the same pdev_id.
