spl: spl_legacy: Fix NAND boot on OMAP3 BeagleBoard
OMAP3 BeagleBoard NAND boot hangs when spl_load_legacy_img() tries
to read the header into 'struct hdr' which is allocated on the
stack.
As the header has already been read once before by spl_nand.c,
we can avoid the extra header allocation and read here by
simply passing around the pointer to the header.
This fixes NAND boot on OMAP3 BeagleBoard.
