From: "Dr. David Alan Gilbert" <linux@treblig.org>
cxgb4_get_srq_entry() has been unused since 2018's commit
e47094751ddc ("cxgb4: Add support to initialise/read SRQ entries")
which added it.
Remove it.
Note: I'm a bit suspicious whether any of the srq code in there
actually does anything useful; without this get I can't see anything
that reads the data, so perhaps the whole thing should go?
But that however would remove one of the opcode handlers, and I have
no way to test that.
