Subject: [PATCH v3] Bluetooth: hidp: using strlcpy instead of strncpy, also
 beautify code.


For NUL terminated string, need always let it ended by zero.

Since have already called memcpy() to initialize 'ci', so need not
redundant initialization.

Better use ''if(session->hid) {} else if(session->input) {}"" instead
of ''if(session->hid) {}; if(session->input) {};''
