i2c: davinci: fixup wait_for_completion_timeout handling
wait_for_completion_timeout return 0 (timeout) or >=1 (completion) so the check
for >= 0 is always true and can be dropped implying that r==-EREMOTEIO and thus
the return of -EREMOTEIO can be done in the if (dev->buf_len) branch.
As wait_for_completion_timeout returns unsigned long not int, and int r is
exclusively used for wait_for_completion_timeout it is renamed and the type
changed to unsigned long.
