[PATCH] scsi: a100u2w: Replace mdelay() with msleep()

[Jia-Ju Bai <baijiaju1990@gmail.com>]

wait_chip_ready() and wait_firmware_ready() are never 
called in atomic context.
They call mdelay() to busily wait, which is not necessary.
mdelay() can be replaced with msleep().

This is found by a static analysis tool named DCNS written by myself.
