[PATCH] usb: host: xhci: fix coverity checker CONSTANT_EXPRESSION_RESULT warning

[Li Jun <jun.li@nxp.com>]

CID 28889612: Operands don't affect result (CONSTANT_EXPRESSION_RESULT)
result_independent_of_operands: urb->transfer_dma >> 16 >> 16 is 0
regardless of the values of its operands. This occurs as an argument
to a function call.

So convert the dma address to be u64 when extract its upper 32 bits.
