of_irq_get_byname() may return 0 as well as negative error number on

would then call request_irq(0, ...) in ti_msgmgr_queue_startup() and never
get a valid channel interrupt.
Check for 'qinst->irq <= 0' instead and return -ENXIO from
ti_msgmgr_queue_setup() and this fail the driver's probe iff
s/this/thus/, sorry for the typo.
of_irq_get_byname() returned 0.
