Josh Law 7fd3213fb5 tools/bootconfig: fix fd leak in load_xbc_file() on fstat failure ...

[ Upstream commit 3b2c2ab4ce ]

If fstat() fails after open() succeeds, the function returns without
closing the file descriptor. Also preserve errno across close(), since
close() may overwrite it before the error is returned.
