On : version, CM

When Calling PCM_OP_ACT_FIND opcode, from valgrind output file  we have identified that memory leak is happening.

# For valgring testing disable BRM internal  memory pool in cm/pin.conf
- - disable_pcm_mempool 1

Memory leak in cm

There shouldn't be memory leak in cm

The issue can be reproduced at will with the following steps:
1. Start CM with valgrind:
e.g /usr/bin/valgrind  --log-file=/tmp/cm_valgrind.vglog --trace-children=yes  --demangle=yes --leak-check=full --show-reachable=yes --track-origins=yes --track-fds=yes --num-callers=48 /pinhome/pinxx/opt/portal/7.5/bin/cm

2. Prepare an input flist (say in.flist)
 0 PIN_FLD_POID POID [0] /service/pcm_client -1 0
 0 PIN_FLD_LOGIN STR [0] "root."

3.  From testnap read this flist and issue PCM_OP_ACT_FIND.
    r in.flist 1
    xop PCM_OP_ACT_FIND 0 1
 4. quit testnap, abort cm started with valgrind. Examine the log file from  valgrind.
     One can see a leak in op_act_find() from cm_custom_ex() level onwards.
