NFSv4: Fix OPEN w/create access mode checking

 * Additional permission checks in order to distinguish between an

 * open for read, and an open for execute. This works around the

 * fact that NFSv4 OPEN treats read and execute permissions as being

 * the same.

 * Note that in the non-execute case, we want to turn off permission

 * checking if we just created a new file (POSIX open() semantics).
