Jan Beulich 5c4e79e29a xenfs/xensyms: respect hypervisor's "next" indication 
The interface specifies the symnum field as an input and output; the
hypervisor sets it to the next sequential symbol's index. xensyms_next()
incrementing the position explicitly (and xensyms_next_sym()
decrementing it to "rewind") is only correct as long as the sequence of
symbol indexes is non-sparse. Use the hypervisor-supplied value instead
to update the position in xensyms_next(), and use the saved incoming
index in xensyms_next_sym().
