qcacld-3.0: Modify the max value of MWS coex ini params
The max ini params for mws_coex_pcc_channel_avoid_delay and
mws_coex_scc_channel_avoid_delay are set to be at 0xFF. This max value
doesnot correspond with the actual max value needed by the firmware.
Change the max value to include upto 0xFFFFFFFF
