    net: ipa: stop using sizeof(status)
    
    The IPA packet status structure changes in IPA v5.0 in ways that
are
    difficult to represent cleanly.  As a small step toward redefining
    it as a parsed block of data, use a constant to define its size,
    rather than the size of the IPA status structure type.

introduced the IPA_STATUS_SIZE constant as a replacent for
sizeof(struct ipa_status). IPA_STATUS_SIZE is defined as
sizeof(__le32[4]), but sizeof(struct ipa_status) = sizeof(__le32[8])
and the newly introducded ipa_status_extract operates on 8 __le32
words, so I wondered if IPA_STATUS_SIZE is correct.
