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.
