Yangyang Li 482d2345bf RDMA/hns: Bugfix for calculation of extended sge 
[ Upstream commit d34895c319faa1e0fc1a48c3b06bba6a8a39ba44 ]

Page alignment is required when setting the number of extended sge
according to the hardware's achivement. If the space of needed extended
sge is greater than one page, the roundup_pow_of_two() can ensure
that. But if the needed extended sge isn't 0 and can not be filled in a
whole page, the driver should align it specifically.
