net: ipa: avoid a bogus warning

Browse Source 
The previous commit added support for IPA having up to six source
and destination resources.  But currently nothing uses more than
four.  (Five of each are used in a newer version of the hardware.)

I find that in one of my build environments the compiler complains
about newly-added code in two spots.  Inspection shows that the
warnings have no merit, but this compiler does not recognize that.

    ipa_main.c:457:39: warning: array index 5 is past the end of the
        array (which contains 4 elements) [-Warray-bounds]
    (and the same warning at line 483)

We can make this warning go away by changing the number of elements
in the source and destination resource limit arrays--now rather than
waiting until we need it to support the newer hardware.  This change
was coming soon anyway; make it now to get rid of the warning.
