x86: create a non-zero sized bm_pte only when needed
Impact: kernel image size reduction
Since in most configurations the pmd page needed maps the same range of
virtual addresses which is also mapped by the earlier inserted one for
covering FIX_DBGP_BASE, that page (and its insertion in the page
tables) can be avoided altogether by detecting the condition at compile
time.
