lib/vsprintf.c: improve sanity check in vsnprintf()
commit 2aa2f9e21e4eb25c720b2e7d80f8929638f6ad73 upstream.
On 64 bit, size may very well be huge even if bit 31 happens to be 0.
Somehow it doesn't feel right that one can pass a 5 GiB buffer but not a
3 GiB one. So cap at INT_MAX as was probably the intention all along.
This is also the made-up value passed by sprintf and vsprintf.
