mtd: rawnand: onfi: Drop a useless parameter page read

Browse source

During detection the logic on the NAND bus is:

    /* Regular ONFI detection */
    1/ read the three NAND parameter pages

    /* Extended parameter page detection */
    2/ send "read the NAND parameter page" commands without reading
       actual data
    3/ move the column pointer to the extended page and read it

If fact, as long as there is nothing happening on the NAND bus between
1/ and 3/, the operation 2/ is redundant so remove it.
