kernel/sysctl.c: remove duplicate UINT_MAX check on do_proc_douintvec_conv()
do_proc_douintvec_conv() has two UINT_MAX checks, we can remove one.
This has no functional changes other than fixing a compiler warning:
kernel/sysctl.c:2190]: (warning) Identical condition '*lvalp>UINT_MAX', second condition is always false
Fixes: 4f2fec00afa60 ("sysctl: simplify unsigned int support")
