Aman Sharma 0584bff096 PCI: Check for platform_get_irq() failure consistently
The platform_get_irq*() interfaces return either a negative error number or
a valid IRQ.  0 is not a valid return value, so check for "< 0" to detect
failure as recommended by the function documentation.

On failure, return the error number from platform_get_irq*() instead of
making up a new one.
