USRPDevice:updateAlignment: remove byteswap code

After upgrading our CI environment to use Debian 12 with GCC 12, the
byteswap code fails the build with the following. I've talked to Eric
about this and he recommended to just remove the code as practically
nobody will use osmo-trx with a big endian system.

USRPDevice.cpp:591:30: error: 'data' is used uninitialized [-Werror=uninitialized]
  591 |   *wordPtr = host_to_usrp_u32(*wordPtr);
      |              ~~~~~~~~~~~~~~~~^~~~~~~~~~
