Viresh Kumar ca8ab593d7 xen: irqfd: Use _IOW instead of the internal _IOC() macro ...

[ Upstream commit 767e33ca47 ]

_IOC() an internal helper that we should not use in driver code.  In
particular, we got the data direction wrong here, which breaks a number
of tools, as having "_IOC_NONE" should never be paired with a nonzero
size.

Use _IOW() instead.
