i2c-highlander: remover superflous variable

Browse Source 
When cppcheck found this flaw

[./i2c/busses/i2c-highlander.c:284]: (style) Warning - using char variable in bit operation

it was noted that the 'read'-variable could be simply removed as read_write can
only be 0 or 1 anyhow. So, we remove the flaw and simplify the code.
