mmc: mmc: fix switch timeout issue caused by jiffies precision

[ Upstream commit 987aa5f8059613bf85cbb6f64ffbd34f5cb7a9d1 ]

with CONFIG_HZ=100, the precision of jiffies is 10ms, and the
generic_cmd6_time of some card is also 10ms. then, may be current
time is only 5ms, but already timed out caused by jiffies precision.
