btrfs: add comments for btrfs_reserve_flush_enum
This enum is the interface exposed to developers.
Although we have a detailed comment explaining the whole idea of space
flushing at the beginning of space-info.c, the exposed enum interface
doesn't have any comment.
Some corner cases, like BTRFS_RESERVE_FLUSH_ALL and
BTRFS_RESERVE_FLUSH_ALL_STEAL can be interrupted by fatal signals, are
not explained at all.
So add some simple comments for these enums as a quick reference.
