[PATCH v2 2/2] fs/sysctl: remove redundant link check in proc_sys_link_fill_cache()

[Danilo Krummrich <danilokrummrich@dk-develop.de>]

proc_sys_link_fill_cache() does not need to check whether we're
called for a link - it's already done by scan().

v2: removed 'err' as it's only used for sysctl_follow_link()
