 modpost: prevent leak when early return no suffix .o in read_symbols() 
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".
And it seems like the suffix ".o" check did not depends on parse_elf()
to succeed first. So, move the suffix ".o" check before checking
parse_elf() result to prevent resource leak when the modname didn't have
suffix ".o" and return early.

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