mmc: meson-gx: Remove setting of CMD_CFG_ERROR

commit 57925e16c9f7d18012bcf45bfa658f92c087981a upstream.

For the t7 and older SoC families, the CMD_CFG_ERROR has no effect.
Starting from SoC family C3, setting this bit without SG LINK data
address will cause the controller to generate an IRQ and stop working.

To fix it, don't set the bit CMD_CFG_ERROR anymore.
