Btrfs: fix overlap of fs_info::flags values
Because the values of BTRFS_FS_EXCL_OP and BTRFS_FS_QUOTA_OVERRIDE overlap,
we should change the value.
First, BTRFS_FS_EXCL_OP was set to 14.
commit 171938e52807 ("btrfs: track exclusive filesystem operation in flags")
Next, the value of BTRFS_FS_QUOTA_OVERRIDE was set to 14.
commit f29efe292198 ("btrfs: add quota override flag to enable quota override for CAP_SYS_RESOURCE")
As a result, the value 14 overlapped, by accident.
This problem is solved by defining the value of BTRFS_FS_EXCL_OP as 16,
the flags are internal.
