mtd: rawnand: fsl_ifc: return errors for failed page reads

fsl_ifc_run_command() logs controller timeout and other non-OPC
completion states in ctrl->nand_stat. fsl_ifc_read_page() then only
increments the ECC failure counter for non-OPC status and still returns
max_bitflips, which can be zero.

Return -ETIMEDOUT when the command did not complete at all and -EIO for
other non-OPC read completions so the NAND core does not treat a failed
page read as a clean page.
