danctnix-besser: ship patch 0002 — filter 5 GHz scans at driver boundary

Adds 0002-bes2600-filter-5ghz-scan.patch on top of the existing
cumulative series, addressing besser issue #1 (recurring
wsm_generic_confirm 0x0007 / [SCAN] Scan failed (-22) pattern).

The fix refuses 5 GHz hw_scan iterations in bes2600_hw_scan; the
firmware-reject cascade for the 5 GHz leg of mac80211's per-band
hw_scan loop is short-circuited.  Source-of-truth commit lives on
marfrit/bes2600-dkms branch bes2600/scan-filter-5ghz (sha 093a503).

Predicted Phase 7 delta: Pattern A rate 14/h -> 0/h. See besser#1
comment 1171 for the full Phase 0-4 analysis and Phase 5 review.

pkgrel bumped to 2.
