tools: gpio-hammer: Avoid potential overflow in main
[ Upstream commit d1ee7e1f5c9191afb69ce46cc7752e4257340a31 ]
If '-o' was used more than 64 times in a single invocation of gpio-hammer,
this could lead to an overflow of the 'lines' array. This commit fixes
this by avoiding the overflow and giving a proper diagnostic back to the
user
