Filipe Manana a52e24c7fc btrfs: fix inode list leak during backref walking at resolve_indirect_refs() 
[ Upstream commit 5614dc3a47e3310fbc77ea3b67eaadd1c6417bf1 ]

During backref walking, at resolve_indirect_refs(), if we get an error
we jump to the 'out' label and call ulist_free() on the 'parents' ulist,
which frees all the elements in the ulist - however that does not free
any inode lists that may be attached to elements, through the 'aux' field
of a ulist node, so we end up leaking lists if we have any attached to
the unodes.

Fix this by calling free_leaf_list() instead of ulist_free() when we exit
from resolve_indirect_refs(). The static function free_leaf_list() is
moved up for this to be possible and it's slightly simplified by removing
unnecessary code.

Fixes: 3301958b7c ("Btrfs: add inodes before dropping the extent lock in find_all_leafs")
