When the 'phba->fcf.fcf_rr_bmask' bitmap is cleared, the code makes the
assumption that it fits in only 1 long.
Depending on the value of LPFC_SLI4_FCF_TBL_INDX_MAX, this may be wrong
and only part of the bitmap would be cleared.
Up to now, LPFC_SLI4_FCF_TBL_INDX_MAX is 32, so it is not an issue. But
using bitmap_zero() is more future proof.
