dump: fix parsing of /proc/locks
dump: fix parsing of /proc/locks

is_blocked should be determined for each line independently.

For example:
1: POSIX  ADVISORY  WRITE 1974 fd:01:392012 0 EOF
2: POSIX  ADVISORY  WRITE 1974 fd:01:392011 0 EOF
3: POSIX  ADVISORY  WRITE 1698 fd:01:1196619 0 EOF
4: POSIX  ADVISORY  WRITE 1698 fd:01:1196620 0 EOF
5: POSIX  ADVISORY  WRITE 1698 fd:01:1196621 0 EOF
6: POSIX  ADVISORY  WRITE 1689 fd:01:1429204 0 EOF
7: POSIX  ADVISORY  WRITE 1690 fd:01:1429202 0 EOF
8: POSIX  ADVISORY  WRITE 1690 fd:01:1429201 0 0
8: -> POSIX  ADVISORY  WRITE 1701 fd:01:1429201 0 0
9: POSIX  ADVISORY  WRITE 1688 fd:01:1429206 0 EOF
10: FLOCK  ADVISORY  WRITE 1694 fd:01:1196520 0 EOF
11: POSIX  ADVISORY  WRITE 862 00:0f:12421 0 EOF
12: POSIX  ADVISORY  WRITE 846 00:0f:12377 0 EOF
13: FLOCK  ADVISORY  WRITE 821 00:0f:11378 0 EOF
14: POSIX  ADVISORY  WRITE 459 00:0f:9826 0 EOF
15: POSIX  ADVISORY  WRITE 511 00:0f:10413 0 EOF

Without this patch crtools returns the error:
(00.000613) Error (proc_parse.c:1089): Invalid file lock info!

It's because is_blocked is set in "true" for the line 8 and
it becomes "true" for the line 9.
