[PATCH net-next 1/2] eth: bnxt: decrease indent in bnxt_init_int_mode()

[Jakub Kicinski <kuba@kernel.org>]

Handle the IRQ table allocation failure right away instead of
wrapping the rest of the function in an if. Purely to make
upcoming changes more readable.

While refactoring, drop the init of rc which is not necessary.

No functional changes.
