NFSv4: Fix unnecessary delegation returns in nfs4_do_open
While nfs4_do_open() expects the fmode argument to be restricted to combinations of FMODE_READ and FMODE_WRITE, both nfs4_atomic_open() and nfs4_proc_create will pass the nfs_open_context->mode, which contains the full fmode_t. This patch ensures that nfs4_do_open strips the other fmode_t bits, fixing a problem in which the nfs4_do_open call would result in an unnecessary delegation return.
