Subject: btrfs: make flush_space take a enum btrfs_flush_state instead of int
Git-commit: 91e79a83fff663283341c8c29293faec8255099a
Patch-mainline: v5.12-rc1
References: bsc#1202528

I got a automated message from somebody who runs clang against our
kernels and it's because I used the wrong enum type for what I passed
into flush_space, caught by -Wenum-conversion.  Change the argument to
be explicitly the enum we're expecting to make everything consistent.
Maybe eventually gcc will catch errors like this.
