[PATCH v3 02/21] vmcore: clean up by removing unnecessary variable

[HATAYAMA Daisuke]

The variable j has int type but it's compared with u64 type.

Also, the purpose of the variable j is exactly what the variable
real_sz is used for now. Replace the variable j by the variable
real_sz and remove the variable j.
