rtl8187: fix 8187B throughput regression
Hin-Tak Leung reported that after the change "rtl8187: add short slot handling for 8187B" his RTL8187B started to give low throughput on network transfers. Turns out that the SIFS setting used isn't ok, it doesn't look to be the real aSIFSTime, using the "magical" 0x22 value like on other 818x variants as the vendor does too fixes the issue.
