[PATCH] Warning fixes

[Pavel Roskin <proski@gnu.org>]

Hello!

I've fixed the trivial stuff, but this may require comments.  I'll be
mostly offline for the next 3 weeks, so if it's OK, please apply it for
me.

ChangeLog:

	* disk/ata.c (grub_ata_pciinit): Mark pciid unused.
	* commands/i386/pc/pxecmd.c (grub_cmd_pxe): Mark argc and args
	unused.
	* include/grub/i386/pc/pxe.h (grub_pxenv_tftp_open): Use char
	instead of grub_uint8_t for strings.
	(grub_pxenv_tftp_get_fsize): Likewise.
