[PATCH] ceph: match wait_for_completion_timeout return type

[Nicholas Mc Guire <hofrat@osadl.org>]

return type of wait_for_completion_timeout is unsigned long not int. An
appropriately named unsigned long is added and the assignment fixed up.

This was only compile tested for x86_64_defconfig + CONFIG_CEPH_FS=m

Patch is against 4.0-rc2 linux-next (localversion-next is -next-20150306)
