gpio: virtuser: fix potential out-of-bound write
[ Upstream commit 7118be7c6072f40391923543fdd1563b8d56377c ]
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.
