i2c: rcar_i2c: Fix i2c read/write errors
commit 7c8f821e5dde ("i2c: rcar_i2c: Set the slave address from
rcar_i2c_xfer") blindly called rcar_i2c_set_addr() with read argument
always set to 1 during xfer which introduced read/write errors, whereas
earlier rcar_i2c_read_common() called rcar_i2c_set_addr() with read set to
1 and rcar_i2c_write_common() called rcar_i2c_set_addr() with read set 0.
Fixes: 7c8f821e5dde ("i2c: rcar_i2c: Set the slave address from rcar_i2c_xfer")
