[PATCH] rbd: reacquire lock should update lock owner client id

[Florian Margaine <florian@platform.sh>]

[-- Attachment #1: Type: text/plain, Size: 748 bytes --]

Otherwise, future operations on this RBD using exclusive-lock are
going to require the lock from a non-existent client id.

This ports commit 475dda114a7e25b43dc9066b9808a64fc0c6dc89 from librbd
to krbd.
