ionic: Fix maybe-uninitialized warning for wqe_size in sq/rq init

Restructure the expdb WQE size logic in sq_init and rq_init to compute
the non-expdb size first, then conditionally upgrade to the expdb size
if supported. This eliminates the -Werror=maybe-uninitialized warning
on wqe_size and simplifies the control flow.
