rtl8187: remove uneeded setting of anaparam write

Usually you set RTL818X_CONFIG3_ANAPARAM_WRITE when you are going to
change/write ANAPARAM registers. But in current initialization of
RTL8187B there is a place where ANAPARAM_WRITE bit is set without any
ANAPARAM register being written, without reason, so remove it.
