[PATCH 1/2] jffs2: fix wrong offset in an error msg from __jff2_dbg_prewrite_paranoia_check

[Cyrille Pitchen]

When a none 0xff character is found in the flash buffer, an error message is
printed. This error message claims to provide the offset of the FIRST corrupted
byte but due to a missing break in the for loop, the former code always prints
the offset of the byte immediately after the end of the tested buffer.
