media: verisilicon: Fix CPU stalls on G2 bus error

In some seek stress tests, we are getting IRQ from the G2 decoder where
the dec_bus_int and the dec_e bits are high, meaning the decoder is
still running despite the error.

Fix this by reworking the IRQ handler to only finish the job once we
have reached completion and move the software reset to when our software
watchdog triggers.

This way, we let the hardware continue on errors when it did not self
reset and in worse case scenario the hardware timeout will
automatically stop it. The actual error will be fixed in a follow up
patch.
