net: ll_temac: Use GFP_KERNEL instead of GFP_ATOMIC when possible
XTE_MAX_JUMBO_FRAME_SIZE is over 9000 bytes and the default value for
'rx_bd_num' is RX_BD_NUM_DEFAULT (i.e. 1024)
So this loop allocates more than 9 Mo of memory.
Previous memory allocations in this function already use GFP_KERNEL, so
use __netdev_alloc_skb_ip_align() and an explicit GFP_KERNEL instead of a
implicit GFP_ATOMIC.
This gives more opportunities of successful allocation.
