    Initialize variables
    
    This patch fixes the following -Werror=maybe-uninitialized errors:
    
    psm_diags.c:294:10: error: 'dst_p' may be used uninitialized in this function [-Werror=maybe-uninitialized]
           if (dst_p) psmi_free(dst_p);
              ^
    In file included from psm_user.h:54:0,
                     from psm_diags.c:35:
    psm_utils.h:156:23: error: 'src_p' may be used uninitialized in this function [-Werror=maybe-uninitialized]
     #define psmi_free(sz) psmi_free_internal(sz)
                           ^
    psm_diags.c:290:11: note: 'src_p' was declared here
         void *src_p, *dst_p;
               ^
    If posix_memalign fails to return a value different than zero,
    the pointers are never initialized.
