usb: typec: wcove: fix uninitialized usbc_irq1 and usbc_irq2
Calls to regmap_read may fail with an -EINVAL return without setting
usbc_irq1 and usbc_irq2. The error handling clean up expects these
to have been set (or zero on a failure) and currently may try to
clear the wrong IRQs if the uninitalized garbage values in usbc_irq1
or usbc_irq2 are non-zero. The simplest fix is to ensure these
variables are initialized to zero.
Detected by CoverityScan, CID#1457737 ("Uninitialized scalar variable")
