Miklos Szeredi b030a2c4a4 vfs: canonicalize create mode in build_open_flags() 
commit e68726ff72 upstream.

Userspace can pass weird create mode in open(2) that we canonicalize to
"(mode & S_IALLUGO) | S_IFREG" in vfs_create().

The problem is that we use the uncanonicalized mode before calling vfs_create()
with unforseen consequences.

So do the canonicalization early in build_open_flags().
