mtd: at91: atmel_nand: return bit flips for the PMECC read_page()
This patch fix pmecc's read_page() to return maximum number of bitflips, 0 if uncorrectable.
In the commit: 3f91e94f7f511de74c0d2abe08672ccdbdd1961c ("mtd: nand: read_page() returns max_bitflips ()"),
The ecc.read_page() is changed to return the maximum number of bitflips.
And when meet uncorrectable bitflips it needs to return 0.
See the comment in nand.h:
* @read_page: function to read a page according to the ECC generator
* requirements; returns maximum number of bitflips corrected in
* any single ECC step, 0 if bitflips uncorrectable, -EIO hw error
