mtd: fix md5sum error checking
In mtd_verify(), the return value of md5sum() has been interpreted as error if nonzero, while the function returns number of processed bytes, which caused mtd_verify() to always fail. This patch fixes error checking to interpret only negative values as errors. Signed-off-by: Zefir Kurtisi <zefir.kurtisi@neratec.com> SVN-Revision: 44605
