commands: i2c_write: enable reg == 0 too
This commit fixes the mistake introduced in the commit 34fadb685905 ('commands: i2c_write: enable raw write to address'). The intended behaviour for i2c_write command is "use raw i2c write only if reg address is not defined". Before the commit 34fadb685905 reg address == 0 was acceptable. After the commit 34fadb685905 reg address == 0 became unacceptable ("undefined") and will lead to raw i2c write.
