pstore/ramoops: Fix ECC parameter help text

In order to set ECC on ramoops, the parameter "ecc" should be
used. The variable that carries this information is "ramoops_ecc".
Due to some confusion in the parameter setting functions, modinfo
ends-up showing both "ecc" and "ramoops_ecc" as valid parameters,
but only "ecc" is the valid one, hence this fix to the parameter
help text.
