Michael Zhilin d471b4f71d usr.sbin/gstat: add microsecond precision for disk latency
This patch makes gstat to show latency in microseconds if actual latency
is less than 1ms. It affects only "ms/r" and "ms/w" columns.

Before patch:
 L(q)  ops/s    r/s   kBps   ms/r    w/s   kBps   ms/w   %busy Name
    0    922      0      0    0.0    922  35809    0.0    2.8| nda0
    0    928      2     34    0.1    926  35809    0.0    3.1| nda1

After patch:
 L(q)  ops/s    r/s   kBps   ms/r    w/s   kBps   ms/w   %busy Name
    0    496      1     31  0.156    495  16020  0.040    1.5| nda0
    0    492      0      0  0.000    492  16020  0.042    1.5| nda1
