If a UMC bad page is reserved but not freed by an application, the
application may trigger uncorrectable error repeatly by accessing the page.
v2: add specific function to do the check.
v3: remove duplicate pages, calculate new added bad page number.
v4: reuse save_bad_pages to calculate new added bad page number.

1. Move the variables of ras block instance members from
specific xxx_ras_fini to general ras_fini call.
2. Function calls inside the modules only use parameters
passed from xxx_ras_fini instead of ras block instance
