kvmvapic: Fix TB invalidation after instruction patching

Since 0b57e287, cpu_memory_rw_debug already triggers a TB invalidation.
As it doesn't (and cannot) set is_cpu_write_access=1 but "consumes" the
currently executed TB, the tb_invalidate_phys_page_range call from
patch_instruction didn't work anymore.

Fix this by open-coding the required bits to restore the CPU state from
the current TB position before patching and resume execution on the
patched instruction afterward.
