Removed check for request or response in IPMB packets coming from
device as well as from host. Now it supports both way communication
to device via IPMB. Both request and response will be passed to
application.

The i2c_client structure can be fairly large, which leads to
a warning about possible kernel stack overflow in some
configurations:
drivers/char/ipmi/ipmb_dev_int.c:115:16: error: stack frame size of 1032 bytes in function 'ipmb_write' [-Werror,-Wframe-larger-than=]
There is no real reason to even declare an i2c_client, as we can simply
call i2c_smbus_xfer() directly instead of the i2c_smbus_write_block_data()
wrapper.
Convert the ipmb_write() to use an open-coded i2c_smbus_write_block_data()
here, without changing the behavior.
It seems that there is another problem with this implementation;
when user space passes a length of more than I2C_SMBUS_BLOCK_MAX
bytes, all the rest is silently ignored. This should probably be
addressed in a separate patch, but I don't know what the intended
behavior is here.
