hv: don't reset hv_context.tsc_page on crash
commit 56ef6718a1d8d77745033c5291e025ce18504159 upstream.
It may happen that secondary CPUs are still alive and resetting
hv_context.tsc_page will cause a consequent crash in read_hv_clock_tsc()
as we don't check for it being not NULL there. It is safe as we're not
freeing this page anyways.
