yushuailong 5de32920f7 drivers/timers: Fix non-atomic clock read in up_timer_gettime. 
up_timer_gettime() computed tv_sec and tv_nsec from two separate calls
to current_usec(), which returns a free-running microsecond counter.
The counter advances between the two calls, so a read that straddles a
second boundary yields an inconsistent (possibly backwards) timespec.

Read current_usec() once into a local variable and derive both fields
from that single snapshot.
