[PATCH 4/4] btrfs: unexport btrfs_qgroup_reserve_meta()

[fdmanana@kernel.org]

From: Filipe Manana <fdmanana@suse.com>

There's only one caller outside qgroup.c of btrfs_qgroup_reserve_meta()
and we have btrfs_qgroup_reserve_meta_prealloc() is a wrapper around
that function. Make that caller use btrfs_qgroup_reserve_meta_prealloc()
and unexport btrfs_qgroup_reserve_meta(), simplifying the external API.
