ceph: fix crash in process_v2_sparse_read() for encrypted directories

The crash in process_v2_sparse_read() for fscrypt-encrypted directories has been reported. Issue takes place for Ceph msgr2 protocol in secure mode. It can be reproduced by the steps:

sudo mount -t ceph :/ /mnt/cephfs/ -o name=admin,fs=cephfs,ms_mode=secure

(1) mkdir /mnt/cephfs/fscrypt-test-3 (2) cp area_decrypted.tar /mnt/cephfs/fscrypt-test-3 (3) fscrypt encrypt --source=raw_key --key=./my.key /mnt/cephfs/fscrypt-test-3 (4) fscrypt lock /mnt/cephfs/fscrypt-test-3 (5) fscrypt unlock --key=my.key /mnt/cephfs/fscrypt-test-3 (6) cat /mnt/cephfs/fscrypt-test-3/area_decrypted.tar (7) Issue has been triggered
