x86/hap: Remove bogus assertion in hap_free_p2m_page()
Coverity ID: 1055622
Coverity correctly points out that this ASSERT() is unconditionally true as an
unsigned integer is always >= 0.
Judging from the shadow counterpart and p2m callsites, there is nothing
invalid about freeing the final p2m page.
