mtd: nand: do not check R/B# for CMD_SET_FEATURES in nand_command(_lp)
Set Features (0xEF) command toggles the R/B# pin after 4 sub feature
parameters are written.
Currently, nand_command(_lp) calls chip->dev_ready immediately after
the address cycle because NAND_CMD_SET_FEATURES falls into default:
label. No wait is needed at this point.
If you see nand_onfi_set_features(), R/B# is already cared by the
chip->waitfunc call.
