arch/x86/postcar_loader: Fix printed MTRR range computation

There is a log message in 'postcar_var_mtrr_set()' showing the used
variable MTRRs which prints the start and the end address as well as the
size of the MTRR region. Instead of the end address the next address
after the end is computed which leads to a wrong log output.

This patch uses 'addr + size - 1' instead of 'addr + size' to compute
the end address correctly.
