drivers/net/wireless: correct check on CCS_START_NETWORK

CCS_START_NETWORK is declared in drivers/net/wireless/rayctl.h with the
comment Values for cmd.  status is previously compared to
CCS_COMMAND_COMPLETE, which is declared in the same file with the comment
Values for buffer_status.  Finally, it is possible at this point that cmd
is CCS_START_NETWORK, because it is compared to that value in an enclosing
switch that has CCS_START_NETWORK as one of two case labels around this code.
