Bluetooth: hidp: NUL terminate a string in the compat ioctl
This change is similar to commit a1616a5ac99e ("Bluetooth: hidp: fix
buffer overflow") but for the compat ioctl. We take a string from the
user and forgot to ensure that it's NUL terminated.
I have also changed the strncpy() in to strscpy() in hidp_setup_hid().
The difference is the strncpy() doesn't necessarily NUL terminate the
destination string. Either change would fix the problem but it's nice
to take a belt and suspenders approach and do both.
