net/bnxt: fix race between interrupt handler and dev config

Fix a possible that while interrupt handler is in the middle of
processing, dev_configure_op() might come in and try to destroy/realloc
the default completion ring on which interrupt completions arrive.
Synchronize the two so they don't race each other
