btrfs-progs: fix improper return value check for is_existing_blk_or_reg_file
The function @is_existing_blk_or_reg_file has a return value of -errno, which indicate the @stat call fails with non-ENOENT errors. In this condition, we should not continue the following work. But -errno evaluates to true and will let the following work go. So we should judge more accurately whether the return value of @is_existing_blk_or_reg_file is > 0 or not to decide our behavior.
