[U-Boot] [PATCH] cmd/gpt.c: Fix warning over memset args in allocate_disk_part

[Tom Rini]

With clang-3.8 we see:
cmd/gpt.c:196:31: warning: 'memset' call operates on objects
      of type 'struct disk_part' while the size is based on a different type
      'struct disk_part *' [-Wsizeof-pointer-memaccess]
        memset(newpart, '\0', sizeof(newpart));
               ~~~~~~~               ^~~~~~~
cmd/gpt.c:196:31: note: did you mean to dereference the
      argument to 'sizeof' (and multiply it by the number of elements)?
        memset(newpart, '\0', sizeof(newpart));
                                     ^~~~~~~

As we should have been passing sizeof(*newpart) not sizeof(newpart)
here.
