[PATCH] namei fixes (8/19)
In open_namei() we never use path.mnt or path.dentry after exit: or ok:.
Assignment of path.dentry in case of LAST_BIND is dead code and only
obfuscates already convoluted function; assignment of path.mnt after
__do_follow_link() can be moved down to the place where we set path.dentry.
Obviously equivalent transformations, just to clean the air a bit in that
region.
