pcmcia/bfin_cf: don't check platform_get_irq's return value against zero
platform_get_irq returns -ENXIO on failure, so !irq was probably
always true. Better use irq <= 0. Note that a return value of
zero is still handled as error even though this could mean irq0.
This is a followup to 305b3228f9
that
changed the return value of platform_get_irq from 0 to -ENXIO on error.
