s390/ctcm: Use GFP_ATOMIC in ctcmpc_tx().
gfp_type() uses in_interrupt() to figure out the correct GFP mask. The usage of in_interrupt() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be separated or the context be conveyed in an argument passed by the caller, which usually knows the context. ctcmpc_tx() is used as net_device_ops::ndo_start_xmit. This callback is invoked with disabled bottom halves. Use GFP_ATOMIC for memory allocation in ctcmpc_tx(). Remove gfp_type() since the last user is gone.
