vfs: canonicalize create mode in build_open_flags()
commit e68726ff72cf7ba5e7d789857fcd9a75ca573f03 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().
