[PATCH] RDMA/restrack: update kernel documentation for ib_create_named_qp()

[Lukas Bulwahn <lukas.bulwahn@gmail.com>]

Commit 66f57b871efc ("RDMA/restrack: Support all QP types") extends
ib_create_qp() to a named ib_create_named_qp(), which takes the caller's
name as argument, but it did not add the new argument description to the
function's kerneldoc.

make htmldocs warns:

  ./drivers/infiniband/core/verbs.c:1206: warning: Function parameter or
  member 'caller' not described in 'ib_create_named_qp'

Add a description for this new argument based on the description of the
same argument in other related functions.
