[Discuss-gnuradio] Fix/Workaround teardown problem in cppdb feature branch

[Stefan Brüns]

Hi,

I have noticed some problem in the cppdb branch (at least) in combination with 
the inband code.

when the usrp instances are destructed, the vector holding the daughterboard 
instances is destructed as well, but there seems to be some problem doing the 
destruction in the right order. Symptoms are: a) deadlock in the inband 
examples, b) gdb stopping in siglongjmp, c) valgrind reporting accesses to 
already freed memory.

The attached small patch fixes this problem.

Stefan
