Andreas Kling a98712035c Kernel: Fix non-blocking write() blocking instead of short-writing ...

If a partial write succeeded, we could then be in an unexpected state
where the file description was non-blocking, but we could no longer
write to it.

Previously, the kernel would block in that state, but instead we now
handle this as a proper short write and return the number of bytes
we were able to write.

Fixes #2645.
