Compiler Attributes: ext4: remove local __nonstring definition

Commit 072ebb3bffe6 ("ext4: add nonstring annotations to ext4.h")
introduced a local definition of __nonstring to suppress some false
positives in gcc 8's -Wstringop-truncation.

Since now we support __nonstring for everyone, remove it.
