[media] v4l2-compat-ioctl32: fix compilation breakage

changeset cfdc3444f5 (v4l: drop v4l2_buffer.input and V4L2_BUF_FLAG_INPUT)
broke compilation on x86_64:

	v4l2-compat-ioctl32.c: In function 'get_v4l2_buffer32':
	v4l2-compat-ioctl32.c:391:4: error: expected ')' before 'return'
	...
	v4l2-compat-ioctl32.c: In function 'put_v4l2_buffer32':
	v4l2-compat-ioctl32.c:475:4: error: expected ')' before 'return'
	...

Add the missing close parenthesis character.
