Filipe Manana 201bb5d745 btrfs: fix silent failure when deleting root reference
commit 47bf225a8d upstream.

At btrfs_del_root_ref(), if btrfs_search_slot() returns an error, we end
up returning from the function with a value of 0 (success). This happens
because the function returns the value stored in the variable 'err',
which is 0, while the error value we got from btrfs_search_slot() is
stored in the 'ret' variable.

So fix it by setting 'err' with the error value.

Fixes: 8289ed9f93 ("btrfs: replace the BUG_ON in btrfs_del_root_ref with proper error handling")
