[PATCH] ltp/fsx: really skip fallocate keep_size calls when replaying ops

[Eryu Guan <eguan@redhat.com>]

On start up, fsx checks for various fallocate(2) operation support
status and disables unsupported operations. But when replaying
operations from a log, fsx failed to skip KEEP_SIZE fallocate(2)
calls if underlying filesystem doesn't support it. For example,
NFSv4.2 supports fallocate(2) but not KEEP_SIZE, and this causes
generic/469 fails on NFSv4.2.

Fix it by taking 'keep_size_calls' into consideration when replaying
ops from log file.

Note that generic/469 hasn't been pushed to upstream yet. Will do in
this week's update.
