[PATCH 2/2] RDMA/bnxt_re: Use common error handling code in bnxt_qplib_alloc_dpi_tbl()

[SF Markus Elfring <elfring@users.sourceforge.net>]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 27 Jan 2018 20:56:56 +0100

Add a jump target so that a bit of exception handling can be better reused
at the end of this function.
