mtd-tests: nandbiterrs: Fix issue that just insert error at bit 7
The function insert_biterror should be designed to insert error at the first '1' bit starting at offset byte. But now, only bit 7 of each byte is checked, because checking mask is always 0x80. So, do right shift for checking mask after each checking to check the whole 8 bits of each bytes.
