bnxt_en: Fix page pool logic for page size >= 64K
[ Upstream commit f6974b4c2d8e1062b5a52228ee47293c15b4ee1e ]
The RXBD length field on all bnxt chips is 16-bit and so we cannot
support a full page when the native page size is 64K or greater.
The non-XDP (non page pool) code path has logic to handle this but
the XDP page pool code path does not handle this. Add the missing
logic to use page_pool_dev_alloc_frag() to allocate 32K chunks if
the page size is 64K or greater.
Fixes: 9f4b28301ce6 ("bnxt: XDP multibuffer enablement")
