Hongling Zeng 37b0dc5e27 parisc: Fix IRQ leak in LASI driver ...

When request_irq() succeeds but gsc_common_setup() fails later,
the IRQ is never released. Fix this by adding proper error handling
with goto labels to ensure resources are released in LIFO order.

Detected by Smatch:
  drivers/parisc/lasi.c:216 lasi_init_chip() warn: 'lasi->gsc_irq.irq'
from request_irq() not released on lines: 207.
