NFSv4: Honour the 'opened' parameter in the atomic_open() filesystem method
Determine if we've created a new file by examining the directory change
attribute and/or the O_EXCL flag.
This fixes a regression when doing a non-exclusive create of a new file.
If the FILE_CREATED flag is not set, the atomic_open() command will
perform full file access permissions checks instead of just checking
for MAY_OPEN.
