usb: typec: Fix unchecked return value
[ Upstream commit e82adc1074a7356f1158233551df9e86b7ebfb82 ]
Currently there is no check on platform_get_irq() return value
in case it fails, hence never actually reporting any errors and
causing unexpected behavior when using such value as argument
for function regmap_irq_get_virq().
Fix this by adding a proper check, a message error and return
*irq* in case platform_get_irq() fails.
