significant slowdown of the mu2e_pcie_utils commands

in addition to the error diagnostics (issue #55) , I'm observing a significant slowdown in execution of the command line single register operations:

mu2etrk@mu2edaq09:~/test_stand/pasha_023>time (my_cntl write 0x9168 0x6824C000 ; my_cntl write 0x916c 0x00000001)

mu2etrk@mu2edaq09:~/test_stand/pasha_023>time rocUtil -a 25 -l 0  simple_read
0 0

real    0m2.073s
user    0m0.016s
sys     0m0.053s

As the result, execution of the mu2e_pcie_utils/dtcInterfaceLib/JAConfig.sh takes more than 25 min.

For comparison, an older version of the mu2e_pcie_utils - below - performs significantly faster:

mu2etrk@mu2edaq09:~/test_stand/pasha_018>time (my_cntl write 0x9168 0x6824C000 ; my_cntl write 0x916c 0x00000001)
sts=0
sts=0

mu2etrk@mu2edaq09:~/test_stand/pasha_018>time rocUtil -a 25 -l 0  simple_read
0 0

real    0m0.130s
user    0m0.017s
sys     0m0.050s

the code in pasha_018 corresponds to mu2e_pcie_utils commit
