nvramtool: cmos_read(): Use malloc() instead of alloca()

Fixes crash occurring when 'nvramtool -a' tried to free a prematurely
freed pointer. (Tested on x60)

malloc() is correct because the pointer is accessed outside the calling
function. The pointer is freed in the parent function list_cmos_entry().
