Amit Virdi 9672f0feb5 usb: core: allow zero packet flag for interrupt urbs
Section 4.4.7.2 "Interrupt Transfer Bandwidth Requirements" of the USB3.0 spec
says:
	A zero-length data payload is a valid transfer and may be useful for
	some implementations.

So, extend the logic of allowing URB_ZERO_PACKET to interrupt urbs too.
Otherwise, the kernel throws warning of BOGUS transfer flags.
