mwifiex: remove function pointer check
clang static analyzer reports this problem
init.c:739:8: warning: Called function pointer
is null (null dereference)
ret = adapter->if_ops.check_fw_status( ...
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In mwifiex_dnld_fw, there is an earlier check for check_fw_status(),
The check was introduced for usb support at the same time this
check in _mwifiex_fw_dpc() was made
if (adapter->if_ops.dnld_fw) {
ret = adapter->if_ops.dnld_fw(adapter, &fw);
} else {
ret = mwifiex_dnld_fw(adapter, &fw);
}
And a dnld_fw function initialized as part the usb's
mwifiex_if_ops.
The other instances of mwifiex_if_ops for pci and sdio
both set check_fw_status.
So the first check is not needed and can be removed.
