libata: limit post SRST nsect/lbal wait to ~100ms
After SRST, libata used to wait for nsect/lbal to be set to 1/1 for
the slave device. However, some ATAPI devices don't set nsect/lbal
after SRST and the wait itself isn't too useful as we're gonna wait
for !BSY right after that anyway.
Before reset-seq update, nsect/lbal wait failure used to be ignored
and caused 30sec delay during detection. After reset-seq, all
timeouts are considered error conditions making libata fail to detect
such ATAPI devices.
This patch limits nsect/lbal wait to around 100ms. This should give
acceptable behavior to such ATAPI devices while not disturbing the
heavily used code path too much.
