fs: dcache: Revert "manually unpoison dname after allocation to shut up kasan's reports"
This reverts commit df4c0e36f1b1782b0611a77c52cc240e5c4752dd. It's no longer needed since dentry_string_cmp() now uses read_word_at_a_time() to avoid kasan's reports. Signed-off-by: Andrey Ryabinin <aryabinin@virtuozzo.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
