LU-4768 tests: Update ost-survey script

Currently, ost-survey hangs due to calling
'lfs setstripe' in an old (positional) style and
setting max_cached_mb to zero.

The call to 'lfs setstripe' is updated to use the
'-S', '-i' and '-c' flags. max_cached_mb is now
set to pagesize * 256 (in MB). The patch also gets
parameters for the correct file system if more
than one Lustre file system is mounted, and
corrects a few typos in comments.

In ll_max_cached_mb_seq_write(), the number of
pages requested is set to the max of pages requested
or PTLRPC_MAX_BRW_PAGES to allow the client to make
well formed RPCs.
