Costa Shulyupin 95fdee73c3 rtla: Fix parse_cpu_set() bug introduced by strtoi() ...

[ Upstream commit 6ea8a20610 ]

The patch 'Replace atoi() with a robust strtoi()' introduced a bug
in parse_cpu_set(), which relies on partial parsing of the input string.

The function parses CPU specifications like '0-3,5' by incrementing
a pointer through the string. strtoi() rejects strings with trailing
characters, causing parse_cpu_set() to fail on any CPU list with
multiple entries.

Restore the original use of atoi() in parse_cpu_set().
