Since commit 87ce9e83ab8b ("memblock, treewide: make memblock_free()
handle late freeing"), both branches of xbc_free_mem() call
memblock_free(), and the early argument has no effect.

memblock_free() also does nothing if addr is NULL, so the check
before the call is redundant.

So remove the argument and the NULL check, and merge _xbc_exit() into
xbc_exit().

No functional change.
