usb: phy: tahvo: add IRQ check
[ Upstream commit 0d45a1373e669880b8beaecc8765f44cb0241e47 ]
The driver neglects to check the result of platform_get_irq()'s call and
blithely passes the negative error codes to request_threaded_irq() (which
takes *unsigned* IRQ #), causing it to fail with -EINVAL, overriding an
original error code. Stop calling request_threaded_irq() with the invalid
IRQ #s.
