Subject: ceph: remove unused and redundant variable dropping
Git-commit: bb0581f01c38ff525295fc6128bc3a49202dabae
Patch-mainline: v4.15-rc1
References: FATE#324714

Variable dropping is set but never read and hence is redundant
and can be removed. Cleans up clang warning:

  fs/ceph/caps.c:1170:2: warning: Value stored to 'dropping' is never read
