checkpatch: test SYMBOLIC_PERMS multiple times per line
There are occasions where symbolic perms are used in a ternary like
return (channel == 0) ? S_IRUGO | S_IWUSR : S_IRUGO;
The current test will find the first use "S_IRUGO | S_IWUSR" but not the
second use "S_IRUGO" on the same line.
Improve the test to look for all instances on a line.
