In the mtk_i2c_irq() handler, variable restart_flag is initialized
to zero and then reassigned with I2C_RS_TRANSFER if and only if
auto_restart is enabled.
Avoid a double initialization of this variable by transferring the
auto_restart check to the restart_flag declaration.
This commit brings no functional changes.
