net: ipa: use struct_size() for the interconnect array 



In review for commit 8ee7ec48 ("net: ipa: embed interconnect
array in the power structure"), Jakub Kicinski suggested that a
follow-up patch use struct_size() when computing the size of the
IPA power structure, which ends with a flexible array member.

Do that.
