Subject: ceph: initialize superblock s_time_gran to 1
Git-commit: 0f7cf80ae96c2a585a00b2cd8b6d24699db47f35
Patch-mainline: v5.3-rc1
References: bsc#1148133

Having granularity set to 1us results in having inode timestamps with a
accurancy different from the fuse client (i.e. atime, ctime and mtime will
always end with '000').  This patch normalizes this behaviour and sets the
granularity to 1.
