kernel-doc: Fix symbol matching for dropped suffixes 



The support for dropping "_noprof" missed dropping the suffix from
exported symbols.  That meant that using the :export: feature would
look for kernel-doc for (eg) krealloc_noprof() and not find the
kernel-doc for krealloc().

Fixes: 51a7bf02 (scripts/kernel-doc: drop "_noprof" on function prototypes)
