exec.c: Don't call cpu_reload_memory_map() from cpu_exec_init()

Currently we call cpu_reload_memory_map() from cpu_exec_init(),
but this is not necessary:
 * KVM doesn't use the data structures maintained by
   cpu_reload_memory_map() (the TLB and cpu->memory_dispatch)
 * for TCG, we will call this function via tcg_commit() either
   as soon as tcg_cpu_address_space_init() registers the listener,
   or when the first MemoryRegion is added to the AddressSpace
   if the AS is empty when we register the listener

The unnecessary call is awkward for adding support for multiple
address spaces per CPU, so drop it.
