IB/srpt: Simplify srpt_handle_tsk_mgmt()
commit 51093254bf879bc9ce96590400a87897c7498463 upstream.
Let the target core check task existence instead of the SRP target
driver. Additionally, let the target core check the validity of the
task management request instead of the ib_srpt driver.
This patch fixes the following kernel crash:
