mtd: tests: nandbiterrs: Fix read_page return value
The number of corrected bitflips is not correctly reported by
the test until the bitflip threshold is reached.
read_page() shall return the number of corrected bitflips, but
mtd_read() returns 0 or a negative error, so we can't forward
its return value. In the absence of an error we always have
calculate the number of bitflips ourselves.
