IB/core: Save QP in ib_flow structure
When we create flow steering rule, we need to save the related QP in the
ib_flow struct. this QP is used in destroy flow.
Move the QP assignment from ib_uverbs_ex_create_flow into ib_create_flow,
this would allow both kernel and userspace consumers to use it.
This bug wasn't seen in the wild because there are no kernel consumers
currently in the kernel.
Fixes: 319a441d1361 ("IB/core: Add receive flow steering support")
