ARM: OMAP3: PM: fix pwrdm_post_transition call sequence
The context lost count is modified in omap_sram_idle() path when pwrdm_post_transition() is called. But pwrdm_post_transition() is called only after omap_gpio_resume_after_idle() is called. Correct this so that context lost count is modified before calling omap_gpio_resume_after_idle(). This would be useful when OMAP GPIO save/restore context is called by the OMAP GPIO driver itself.
