firmware-samsung-i9100: use a slightly newer bcmdhd_sta.bin (MR 5571)

The one we switch to has version 5.90.100.43, while original one has
version 5.90.100.41 (can be checked with: `strings bcmdhd_sta.bin |
tail -n1`). The p4wifi tablet is also using the same blob (but
downloaded from elsewhere).

I believe the blob originates from the msm version of galaxy s2, with
codename "skyrocket".  It seems to be the newest blob for brcm4330b1
available.  The linux-firmware repo only has a blob for brcm4330b2,
which does not work for i9100.

Unfortunately even with latest available firmware blob mainline linux
still prints errors like:

[  593.513854] ieee80211 phy1: brcmf_proto_bcdc_query_dcmd: brcmf_proto_bcdc_msg failed w/status -110
[  593.513926] ieee80211 phy1: brcmf_cfg80211_dump_station: BRCMF_C_GET_ASSOCLIST failed, err=-110

a few times per minute.
