Ioana Ciornei 7aaa0f311e dpaa2-switch: seed the buffer pool after allocating the swp
Any interraction with the buffer pool (seeding a buffer, acquire one) is
made through a software portal (SWP, a DPIO object).
There are circumstances where the dpaa2-switch driver probes on a DPSW
before any DPIO devices have been probed. In this case, seeding of the
buffer pool will lead to a panic since no SWPs are initialized.

To fix this, seed the buffer pool after making sure that the software
portals have been probed and are ready to be used.
