caif: Replace memset(0) + strscpy() with strscpy_pad()

Browse Source 
Replace memset(0) followed by strscpy() with strscpy_pad() to improve
cfctrl_linkup_request(). This avoids zeroing the memory before copying
the string and ensures the destination buffer is only written to once,
simplifying the code and improving efficiency.
