mtd: rawnand: sunxi: change error prone variable name

In sunxi_nand_hw_ecc_ctrl_init(), i is used as a loop index variable and
at the same time as the value used to set ECC mode in ECC control
register.
To prevent it from being re-used as a loop variable, let's change the
naming to ecc_mode.

No functional change.
