RDMA/pvrdma: Use non-atomic bitmap functions when possible
In 'pvrdma_uar_table_init()', the 'tbl->table' bitmap has just been
allocated, so no concurrent accesses can occur.
The other accesses to the 'tbl->table' bitmap are protected by the
'tbl->lock' spinlock, so no concurrent accesses can happen.
So prefer the non-atomic '__[set|clear]_bit()' functions to save a few
cycles.
