staging: gpib: agilent usb console messaging cleanup

Enable module name to be printed in pr_xxx and dev_xxx
Use DRV_NAME defined as KBUILD_MODNAME instead of hard coded
string in usb_driver struct.

Remove __func__ parameter in dev_dbg messages as this can be
enabled with dynamic debug.

Remove __func__ parameter in dev_err messages as they are not
needed. The module name is sufficient.

Change pr_info to dev_dbg where needed and remove the rest
where possible.

Remove test and error messages for buffer over run in write and
read_registers as these are just trying to catch bugs in the driver.

Remove agilent_82357a string prefix in error messages.

Return -EIO for too many reads in read_registers instead of
continuing after printing an error message.

Change pr_warn to dev_warn.

Remove warning on calls for unsupported functionality.

Remove test and message for buffer overflow in agilent_82357_init
and agilent_82357a_go_idle which are just checking for a driver bug.
Use actual indeces in the array instead of i and then incrementing
i so that the code is clear and there is no need to check for
overflow or print a message.
