[PATCH] xen/pvcalls: remove redundant check for irq >= 0

[Colin King <colin.king@canonical.com>]

From: Colin Ian King <colin.king@canonical.com>

This is a moot point, but irq is always less than zero at the label
out_error, so the check for irq >= 0 is redundant and can be removed.

Detected by CoverityScan, CID#1460371 ("Logically dead code")

Fixes: cb1c7d9bbc87 ("xen/pvcalls: implement connect command")
