[PATCH 2/3] i2c: xlr: fix extra read/write at end of rx transfer

The BYTECNT register holds the transfer size minus one. Setting it to the correct value requires a dummy read/write only for zero-length transfers as it is impossible to request one from the hardware. If a zero-length transfer is requested, changing the length to 1 and setting "buf" to a dummy
