[PATCH] PCI: dwc: Fix a 64bit bug in dw_pcie_ep_raise_msix_irq()

[Dan Carpenter <dan.carpenter@linaro.org>]

The "msg_addr" variable is u64.  However, the "tbl_offset" is an unsigned
int.  This means that when the code does

	msg_addr &= ~aligned_offset;

it will unintentionally zero out the high 32 bits.  Declare "tbl_offset"
as a u64 to address this bug.
