gpio: pca953x: fix cache_only and IRQ state on restore_context() failure

When pca953x_restore_context() fails, cache_only is left disabled and
the IRQ left enabled, even though register synchronization may not have
completed successfully. Restore cache_only and disable the IRQ again on
failure, matching the state set by pca953x_save_context().

Fixes: ec5bde62019b ("gpio: pca953x: Split pca953x_restore_context() and pca953x_save_context()")
