mem: fix page_table bug for .fast build
Since b8b13206c8, the '.fast' build has failed to compile with an error caused by a variable and an assert. As a reminder, assert macros are optimized out of the build for '.fast'. If an assert check requires a variable that is unused anywhere else in the code, the compiler complains that the variable is unused and the scons build fails. The solution is to add a M5_VAR_USED specifier to tell the compiler to ignore the variable.
