[PATCH] firewire: init_ohci1394_dma: Replace mdelay with msleep

[PATCH] firewire: init_ohci1394_dma: Replace mdelay with msleep

[Jia-Ju Bai]

init_ohci1394_wait_for_busresets() and
init_ohci1394_reset_and_init_dma() 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.
