[PATCH] psi: Prepend "0x" to format specifiers when printing PSI flags

[K Prateek Nayak]

It is not immediately clear that the PSI flags, the set, and the clear
bits printed in PSI warnings are hexadecimal values. Prepend "0x" to
format specifiers to make it clear.

Since "kernel/sched" uses "0x%x" as opposed to "%#x" when printing
hexadecimal values, the same was followed to keep consistency.
