[PATCH 2/2] smb: client: remove unnecessary NULL check in open_cached_dir_by_dentry()

[Henrique Carvalho <henrique.carvalho@suse.com>]

The function open_cached_dir_by_dentry() is only called by
cifs_dentry_needs_reval(), and it always passes dentry->d_parent as the
argument to dentry.

Since dentry->d_parent cannot be NULL, the check for dentry == NULL
is unnecessary and can be removed.
