qcacld-3.0: Define new_ch_width in csa_offload_params as phy_ch_width

Currently sme_switch_channel set new_ch_width as phy_ch_width, while
wma_csa_offload_handler set new_ch_width as raw bit in wide bandwidth
channel switch IE.
Clean up the code. Define new_ch_width in csa_offload_params as
phy_ch_width.
