i2c: smbus: fix NULL function pointer dereference
In the Linux kernel, the following vulnerability has been resolved: i2c: smbus: fix NULL function pointer dereference Baruch reported an OOPS when using the designware controller as target only. Target-only modes break the assumption of one transfer function always being available. Fix this by always checking the pointer in __i2c_transfer. [wsa: dropped the simplification in core-smbus to avoid theoretical regressions]
