bnxt_en: Free context memory in the open path if firmware has been reset.

[ Upstream commit 325f85f37e5b35807d86185bdf2c64d2980c44ba ]

This will trigger new context memory to be rediscovered and allocated
during the re-probe process after a firmware reset.  Without this, the
newly reset firmware does not have valid context memory and the driver
will eventually fail to allocate some resources.
