* disk/ata.c (grub_ata_wait_not_busy): Add debug output of status
	register.
	(grub_atapi_identify): Add wait after drive select.
	(grub_ata_identify): Do more strict status register check before
	calling grub_atapi_identify ().  Suppress error message if status
	register is 0x00 after command failure.  Add status register
	check after PIO read to avoid bogus identify due to stuck DRQ.
	Thanks to Pavel Roskin for testing.
	(grub_device_initialize): Remove unsafe status register check.
	Thanks to 'phcoder' for problem report and patch.
	Prevent sign extension in debug message.
