Leandro Pereira 25fb83c6e0 drivers: i2c: Fix TOCTOU while transferring I2C messages 
All the mesages are checked with _SYSCALL_MEMORY() prior to calling the
actual implementation function.  However, a race condition might happen
between the check and the call to _impl_i2c_transfer() itself.

Copy the msgs vector to a locally allocated array and pass it to the
transfer implementation.
