Subject: mm/memblock.c: reversed logic in memblock_discard()

From: Pavel Tatashin <[email protected]>

commit 91b540f98872a206ea1c49e4aa6ea8eed0886644 upstream.

In recently introduced memblock_discard() there is a reversed logic bug. Memory is freed of static array instead of dynamically allocated one.
