genirq/msi: Fix off-by-one error in msi_domain_alloc()
The error path in msi_domain_alloc(), frees the already allocated MSI
interrupts in a loop, but the loop condition terminates when the index
reaches zero, which fails to free the first allocated MSI interrupt at
index zero.
Check for >= 0 so that msi[0] is freed as well.
Fixes: f3cf8bb0d6c3 ("genirq: Add generic msi irq domain support")
