Markus Burri afe090366f gpio: virtuser: fix potential out-of-bound write ...

[ Upstream commit 7118be7c60 ]

If the caller wrote more characters, count is truncated to the max
available space in "simple_write_to_buffer". Check that the input
size does not exceed the buffer size. Write a zero termination
afterwards.
