Subject: USB: kobil_sct: fix non-atomic allocation in write path

From: Johan Hovold <johan@xxxxxxxxxx>

commit 191252837626fca0de694c18bb2aa64c118eda89 upstream.

Write may be called from interrupt context so make sure to use
GFP_ATOMIC for all allocations in write.

Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
