RDMA/hns: Refactor mtr find

Browse source 
[ Upstream commit a4ca341080 ]

hns_roce_mtr_find() is a collection of multiple functions, and the
return value is also difficult to understand, which is not conducive
to modification and maintenance.

Separate the function of obtaining MTR root BA from this function.
And some adjustments has been made to improve readability.
