time/jiffies: Fix sysctl file error on configurations where USER_HZ < HZ

Browse source

Commit 2dc164a48e ("sysctl: Create converter functions with two new
macros") incorrectly returns error to user space when jiffies sysctl
converter is used. The old overflow check got replaced with an
unconditional one:
     +    if (USER_HZ < HZ)
     +        return -EINVAL;
which will always be true on configurations with "USER_HZ < HZ".

Remove the check; it is no longer needed as clock_t_to_jiffies() returns
ULONG_MAX for the overflow case and proc_int_u2k_conv_uop() checks for
"> INT_MAX" after conversion
