audit: Convert int limit uses to u32
The equivalent uapi struct uses __u32 so make the kernel uses u32 too. This can prevent some oddities where the limit is logged/emitted as a negative value. Convert kstrtol to kstrtouint to disallow negative values. Signed-off-by: Joe Perches <joe@perches.com> [eparis: do not remove static from audit_default declaration]
