Here are some more fixes for the eHCA driver, fixing some problems we found
during internal system test.
[1/5] fixes the QP pointer determination for SRQ base QPs
[2/5] fixes a masking error in {,re}reg_phys_mr()
[3/5] fixes a bug in alloc_fmr() and simplifies some code
[4/5] refactors
Because hardware reports the SRQ token in RWQEs of SRQ base QPs, supply the
base QP token as SRQ token, so we can properly find the SRQ base QP.

So this is really just like synchronize_irq()? Using msleep is bogus
because you want to spin, you are only waiting for a softirq on the other
cpu to finish. If you wait for a whole millisecond and sleep that
is far longer than the napi routine should take.
