exec: fix breakpoint_invalidate when pc may not be translated 

This fixes qemu abort with the following message:

    include/qemu/int128.h:22: int128_get64: Assertion `!a.hi' failed.

which happens due to attempt to invalidate breakpoint by virtual address
for which get_phys_page_debug couldn't find mapping.
