[LTP] [PATCH 1/2] docparse/docparse.c: Split the process of implied flags

[Xiao Yang]

Check implied flags in one loop and set implied flags in another
loop so that the following false positive can be avoided:
----------------------------------------------------
# docparse/docparse testcases/kernel/syscalls/chdir/chdir01.c
testcases/kernel/syscalls/chdir/chdir01.c: useless tag: needs_device
...
----------------------------------------------------
