Subject: [PATCH] ceph: remove unused and redundant variable dropping

From: Colin Ian King <colin.king@...onical.com>

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
