[LEDE-DEV] [PATCH mountd 4/5] mountd: Fix unused result in mount.c for symlink()

[Florian Fainelli]

Fixes the following warning:

mountd-2016-12-19-dd5799c9/mount.c:454:3: note: each undeclared identifier is reported only once for each function it appears in
mountd-2016-12-19-dd5799c9/mount.c: In function 'mount_add_list':
mountd-2016-12-19-dd5799c9/mount.c:163:10: error: ignoring return value of 'symlink', declared with attribute warn_unused_result [-Werror=unused-result]
   symlink(tmp2, tmp);
          ^
