s390/qeth: allocate initial TX Buffer structs with GFP_KERNEL
qeth_init_qdio_out_buf() is typically called during initialization, and the GFP_ATOMIC is only needed for a very specific & rare case during TX completion. Allow callers to specify a gfp mask, so that the initialization path can select GFP_KERNEL. While at it also clarify the function name.
