pda_power: Check and handle return value of set_irq_wake

The recent change in commit 2db873211ba47ef704c301f9ecf4a33413a0b649
forces the calls enable_irq_wake() and disable_irq_wake() to
be balanced. But if in pda_power_suspend() the call to
enable_irq_wake() fails (because attached gpio cannot wake
up the CPU), the corresponding disable_irq_wake will WARN().
Fix it by storing success/failure of enable_irq_wake().
