[PATCH] remove unlikely(sb) in prune_dcache

likely profiling shows that the following is a miss.

After boot:
[+- ] Type | # True | # False | Function:Filename@Line
+unlikely |     1074|        0  prune_dcache()@:fs/dcache.c@409

After a bonnie++ run:
+unlikely |    66716|    19584  prune_dcache()@:fs/dcache.c@409

So remove it.
