[PATCH 10/18] qla2xxx: prevent bounds-check bypass via speculative execution

Static analysis reports that 'handle' may be a user controlled value that is used as a data dependency to read 'sp' from the 'req->outstanding_cmds' array. In order to avoid potential leaks of kernel memory values, block speculative execution of the instruction stream that could issue reads based
