[PATCH] modpost: release allocation when early return no suffix .o in read_symbols()

[Robertus Diawan Chris]

The allocation for elf info symsearch and hdr from parse_elf() haven't
been released when return because of modname didn't have suffix ".o".
So, release the allocation before early return because of modname
without suffix ".o".

This is reported by Coverity Scan as "Resource leak".
