rtl8187: Fix error in setting OFDM power settings for RTL8187L
commit eb83bbf57429ab80f49b413e3e44d3b19c3fdc5a upstream.
After reports of poor performance, a review of the latest vendor driver
(rtl8187_linux_26.1025.0328.2007) for RTL8187L devices was undertaken.
A difference was found in the code used to index the OFDM power tables. When
the Linux driver was changed, my unit works at a much greater range than
before. I think this fixes Bugzilla #12380 and has been tested by at least
two other users.
