of: reserved-memory: Do not make kmemleak ignore freed address

early_init_dt_alloc_reserved_memory_arch() will free address @base when
suffers memblock_mark_nomap() error, but it still makes kmemleak ignore
the freed address @base via kmemleak_ignore_phys().

That is unnecessary, besides, also causes unnecessary warning messages:

kmemleak_ignore_phys()
 -> make_black_object()
    -> paint_ptr()
       -> kmemleak_warn() // warning message here.

Fix by avoiding kmemleak_ignore_phys() when suffer the error.
