at91: fix enable/disable_irq_wake symmetry in pcmcia driver

Browse source 
Fix enable_irq_wake and disable_irq_wake symmetry in at91 pcmcia driver

disable_irq_wake call must be symmetric with enable_irq_wake.  This patch
fix that problem for the at91_pcmia driver.  It seems that this patch was
forgotten when we've fixed irq_wake symmetry in all at91 related drivers.
It was discussed in the "at91 drivers and [enable/disable]_irq_wake
(wrong?) usage" thread on the linux-arm-kernel mailing list.
