staging/rdma/hfi1: Reduce snoop locking scope in IOCTL handler.

Browse source

This patch avoids issues while calling into copy from/to user while holding the
lock by only taking the lock when it is absolutely required.

The only commands which require the snoop lock are: *Set Filter *Clear Filter
*Clear Queue
