Add header file <linux/limits.h> to make thread_info.h be
self-contained.
Fixes multiple occurrences of this error:
../include/linux/thread_info.h: In function ‘check_copy_size’:
../include/linux/thread_info.h:215:27: error: ‘INT_MAX’ undeclared (first use in this function)
if (WARN_ON_ONCE(bytes > INT_MAX))
^
Fixes: 6d13de1489b6 ("uaccess: disallow > INT_MAX copy sizes")
