LINUX: consolidate duplicate code in osi_TryEvictDentries
The two stanzas for HAVE_DCACHE_LOCK are now functionally identical;
remove the preprocessor conditionals and duplicate code.
Minor functional change is incurrred for very old (before 2.6.38) Linux
versions that have dcache_lock; we are now obtaining the d_lock as well.
This is safe because d_lock is also quite old (pre-git, 2.6.12), and it
is a spinlock that's only held for checking d_unhashed. Therefore, it
should have negligible performance impact. It cannot cause deadlocks or
violate locking order, because spinlocks can't be held across sleeps.
