Revert "increase requested memory from LSF for the Pindel job"

This reverts commit 5dd8ff26cd3bb16bfb3cdfe1d9a0ea2d987bc8b0.  This is a
Workflow server so cannot and should not have this much memory
requested.  This was discovered because it was recently changed to run
in the workflow queue instead of in the long queue.
