qcacld-3.0: fix compile error in cdp_fc_get_tx_resource API

cdp_fc_get_tx_resource API is being called without passing
pdev handle, which mis-matches the prototype. Adding a fix
to include right arguments to passed, also removing static
from function ol_txrx_get_vdev_by_peer_addr to expose scope
outside the file, to fix compile errors.
