Keith reported the following warning:
WARNING: CPU: 28 PID: 1420 at kernel/irq/matrix.c:222 irq_matrix_remove_managed+0x10f/0x120
x86_vector_free_irqs+0xa1/0x180
x86_vector_alloc_irqs+0x1e4/0x3a0
msi_domain_alloc+0x62/0x130
The reason for this is that if the vector allocation fails the error
handling code tries to free the failed vector as well, which causes the
above imbalance warning to trigger.
Adjust the error path to handle this correctly.
