A Coverity static code scan raised a potential overflow_before_widen
warning when hfi_features::nr_table_pages is used as an argument to
memcpy in intel_hfi_process_event().
Even though the overflow can never happen (the maximum number of pages of
the HFI table is 0x10 and 0x10 << PAGE_SHIFT = 0x10000), using size_t as
the data type of hfi_features::nr_table_pages makes Coverity happy and
matches the data type of the argument 'size' of memcpy().
