[PATCH 44/53] hostfs: don't d_drop() before d_splice_alias() in hostfs_mkdir()

[NeilBrown]

From: NeilBrown <n...@brown.name>

hostfs_mkdir() uses d_drop() and d_splice_alias() to ensure it has the
right dentry after a mkdir.
d_drop() is no longer needed here and will cause problem for future
changes to directory locking.  So remove the d_drop().
