usb: langwell_udc: Fix max packet size calculations

This patch is used to fix max packet size issue in langwell_udc
controller driver.  As max packct size is 1024 for ISO transfer, 0x7ff
(bit 0~10) should be used to compute the value. If 0x8ff is used, the
value may be wrongly set as 0 instead of 1024 or 512.
