anolis: mm: change del_pid permission to write only 

commit 0f657097a26be0ae7a39cedbcfe0fa53fa81961c openAnolis

Conflicts: Picked from 5.4.

Backport-reason: Add code segment unevictable feature support [PATCH 3/8]

ANBZ: #1871

/proc/unevictable/del_pid has mode 0600 but no read implementation,
which will fail testcase ltp_fs_proc01. So change it to appropriate mode.
