bnxt_en: resize bnxt_irq name field to fit format string

The name field of struct bnxt_irq is written using snprintf in
bnxt_setup_msix(). Make the field large enough to fit the maximal
formatted string to prevent truncation.  Truncated IRQ names are
less meaningful to the user.  For example, "enp4s0f0np0-TxRx-0"
gets truncated to "enp4s0f0np0-TxRx-" with the existing code.

Make sure we have space for the extra characters added to the IRQ
names:

  - the characters introduced by the static format string: hyphens
  - the maximal static substituted ring type string: "TxRx"
  - the maximum length of an integer formatted as a string, even
    though reasonable ring numbers would never be as long as this.
