nandtest: print number of bits corrected during test
The nandtest program monitors the corrected ecc stat to determine if an ECC correction has taken place during the last write-read. If so, it prints "ECC corrected". The mtd subsytem will store the number of bits corrected in the corrected ecc stat so update the nandtest output to print also the number of bits corrected when performing the test.
