commit 725606a41de5bfbaba683fa554cdb35c83895d19

    Fix handling of multiple contexts with a remote namespace.
    
    Found this issue when investgating a pmdumptext failure in 027
    from the pcp-gui tests.
    
    This dumps core when trying to acquire a context-specific lock
    due to a null pointer dereference on the c_pmcd->pc_lock field.
    In local context mode, c_pmcd is null.  With the right (wrong?)
    combination of local and remote contexts, a scenario where a
    remote context lock is attempted on a local context.
    
    Root cause is an incorrect assignment during an if (...) test.
    The braces were in the wrong position, causing the assignment
    to not be the return value from __pmWhichContext, but rather
    the result of the 'if (pmWhichContext() < 0)' test.  Argh!
