rtl8187: Fix wrong rfkill switch mask for some models

Browse Source 
There are different bits used to convey the setting of the rfkill
switch to the driver. The current driver only supports one of these
possibilities. These changes were derived from the latest version
of the vendor driver.

This patch fixes the regression noted in kernel Bugzilla #14743.
