[PATCH] HID: picoLCD: Remove use of deprecated function

The flush_delayed_work_sync function is deprecated,
we can instead call flush_delayed_work directly.

Sparse is giving a warning:
drivers/hid/hid-picolcd_fb.c:611:2: warning:
	‘flush_delayed_work_sync’ is deprecated
	(declared at include/linux/workqueue.h:454)
	[-Wdeprecated-declarations]
