  gnrc_ipv6: remove superfluous release

The packet handed to `_fill_ipv6_hdr()` is already released in the
caller (in the current version this is only `_save_fill_ipv6_hdr()`).

  gnrc_ipv6: correctly reset from temporary variable

While `tmp` in the loop for write-protection for the check-sum
calculation is used to check the return value of
`gnrc_pktbuf_start_write()`, it was never overwriting `payload` causing
the original snip to be used in the following iteration `prev` when
duplicated, and destroying the sanity of `ipv6`.

  Log Message:
  -----------
  gnrc_ipv6: refactor to remove superfluous temporary variable

Since no release in this function is required anyways, we can just use
`payload` to check the return value directly.
