staging: rtl8712: unterminated string leads to read overflow
The memdup_user() function does not necessarily return a NUL terminated
string so this can lead to a read overflow. Switch from memdup_user()
to strndup_user() to fix this bug.
Fixes: c6dc001f2add ("staging: r8712u: Merging Realtek's latest (v2.6.6). Various fixes.")
