Keep TX and RX buffers on EFI rather than always allocate new ones.

Browse source 
* include/grub/net.h (grub_net_card_driver): Allow driver to modify
	card. All users updated.
	(grub_net_card): New members txbuf, rcvbuf, rcvbufsize and txbusy.
	* grub-core/net/drivers/efi/efinet.c (send_card_buffer): Reuse buffer.
	(get_card_packet): Likewise.
	(grub_efinet_findcards): Init new fields.
