Xiaoyao Li 792cb90e84 memory: Set mr->ram before RAM Block allocation ...

Commit 2fb627ef2f ("memory: Factor out common ram region initialization")
introduced a helper function memory_region_set_ram_block(), which causes
mr->ram to be set to true after the RAM Block allocation by
qemu_ram_alloc_*().

It leads to the assertion

  g_assert(memory_region_is_ram(mr));

in memory_region_set_ram_discard_manager() being triggered when creating
RAM Block with the RAM_GUEST_MEMFD flag.

Fix this by restoring the original behavior of setting mr->ram before
RAM Block allocation.
