libext2fs: fix infinite loop if copying in an empty directory

In m_minrootdir, on FreeBSD 9.3, try_lseek_copy() fails on an empty file
because errcode is uninitialized and the while() loop never executes,
and the errcode garbage is returned.

Initialize errcode = 0 in try_lseek_copy() to avoid a "fail" result when
there was nothing to copy.
