[PATCH] ceph: remove unused and redundant variable dropping

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

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
