nfsd: (almost) always open file in nfsd4_create_file()

If the file is found to already exist, open it anyway.  This will
normally be needed eventually anyway, and providing a consistently valid
op_filp will simplify future changes.

To simplify this, change nfsd_check_obj_isreg() to take a dentry.

This doesn't apply in the case where the file was found in the dcache to
be mounted-on.  That takes a different path and doesn't require an early
open.
