Bartosz Golaszewski 4e15415930 gpiolib: improve the robustness of watch/unwatch ioctl() 
This makes the new ioctl() a bit more robust - we now check if a line
is already being watched and return -EBUSY if the user-space tries to
start watching it again. Same for unwatch - return -EBUSY if user-space
tries to unwatch a line that's not being watched.

Fixes: 51c1064e82 ("gpiolib: add new ioctl() for monitoring changes in line info")
