[PATCH] crec: Always read whole number of fragments when length limit specified

[Richard Fitzgerald <rf@opensource.wolfsonmicro.com>]

This patch removes the lines that adjusted the read size to exactly
read to the end of the calculated length in bytes. Doing this could
lead to invalid fragment sizes being requested which may then cause
a read error on some codecs.

Instead we keep reading whole fragments until we have >= length bytes
of data captured.
