[PATCH 10/14] lib/bootconfig: drop redundant memset of xbc_nodes

[Josh Law <objecting@objecting.org>]

memblock_alloc() already returns zeroed memory, so the explicit memset
in xbc_init() is redundant. Switch the userspace xbc_alloc_mem() from
malloc() to calloc() so both paths return zeroed memory, and remove
the separate memset call.
