yushuailong 7e67d2d906 libs/libc/dirent: preserve errno on readdir() end-of-directory ... readdir() returned NULL at end-of-directory without ensuring errno was clean. POSIX requires errno to be unchanged at EOF, but the underlying read() path may leave a stale errno value. Callers that follow the POSIX idiom (set errno to 0 before the call, test it after a NULL return), such as readdir_r() and scandir(), then misread this as a readdir() failure. Save errno on entry and restore it on the end-of-directory return so that EOF no longer reports a spurious error, while genuine errors (read() returning a negative value) still propagate.
