usb: phy: fsl-usb: add IRQ check
[ Upstream commit ecc2f30dbb25969908115c81ec23650ed982b004 ]
The driver neglects to check the result of platform_get_irq()'s call and
blithely passes the negative error codes to request_irq() (which takes
*unsigned* IRQ #), causing it to fail with -EINVAL, overriding an original
error code. Stop calling request_irq() with the invalid IRQ #s.
