wifi: iwlwifi: fix out of bound copy_from_user
The driver copies the userspace buffer into an internal NUL
byte terminated buffer. While doing so, it was reading beyond
the end of the userspace buffer, overwriting its own NUL
termination in the process.
Fix this by only copying the correct number of bytes.
