Dean Luick 7b3256e331 IB/hfi1: Fix user SDMA racy user request claim 
The user SDMA in-use claim bit is in the structure that gets zeroed out
once the claim is made.  Move the request in-use flag into its own bit
array and use that for atomic claims.  This cleans up the claim code and
removes any race possibility.
