ovl: make ovl_create_real() cope with vfs_mkdir() safely
vfs_mkdir() may succeed and leave the dentry passed to it unhashed and
negative. ovl_create_real() is the last caller breaking when that
happens.
[amir: split re-factoring of ovl_create_temp() to prep patch
add comment about unhashed dir after mkdir
add pr_warn() if mkdir succeeds and lookup fails]
