The timeout in ufshci_sim_find_periph() is uint64_t, making the
comparison of timeout - ticks with zero always false. If the requested
peripheral does not become available, the lookup can wait indefinitely.
Use an sbintime_t deadline based on sbinuptime() and mstosbt(), and
compare the current uptime directly with the deadline. Preserve the
successful lookup path and existing timeout cleanup.
On an HP 15-fd0118ca with Intel N150 and Samsung UFS 3.1 storage, a
kernel built from stable/15 revision 84aa3cb3204d with this change
logged the missing-WLUN timeout, attached da0 and mounted root in two
boot trials.
