[PATCH 3/7] drivers/usb/gadget/pch_udc.c: adjust suspicious bit operation

From: Julia Lawall <redacted>

PCH_UDC_DMA_LAST is 0x08000000 so a bit-or with this value always gives a
nonzero result.  The test is rewritten as done elsewhere in the same file.

This problem was found using Coccinelle (http://coccinelle.lip6.fr/).
