net: ipa: avoid a bogus warning
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 (Five of each are used in a newer version of the hardware.)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.
