qcacld-3.0: Remove obsolete csr_api_roam functions

While trying to enable the -Wmissing-prototypes compiler switch the
following obsolete APIs were uncovered in csr_api_roam.c:
	csr_roam_get_phy_mode_from_dot11_mode()
	csr_get_htcb_state_from_vhtcb_state()
	csr_is_command_waiting()

Since these are obsolete, remove them.
