staging: rtl8723bs: remove overwriting of current IMR settings

Originally, this code use to
	Step 1: Read a value from register
	Step 2: Add some bits to the value
	Step 3: Write the result back to the same register

The problem was that the bits in Step 2 were always zero and didn't
change the value, so I have removed that code. Now this function
just reads a value and writes the same value back. It is unnecessary
and can be removed.
