[PATCH 1/2] fuse: don't d_drop() before d_splice_alias()

[NeilBrown]

From: NeilBrown <neil@xxxxxxxxxx>

create_new_entry() is used to finalise the creation of various
objects (mknod, mkdir, symlink etc).

It currently uses d_drop() which will be a problem for a proposed
new locking scheme.

d_splice_alias() now works on hashed dentries so the d_drop() isn't
needed.  Drop it.
