Fix incorrect Memory Search variable name

[sjanusz-r7]

This PR fixes a small mistake introduced by my previous commit, where a variable was being shadowed, but not all occurrences were fixed resulting in a hanging process.

After

I rebuilt the solution, and ran:

cp ~/Desktop/Programming/metasploit-payloads/c/meterpreter/output/* /z/meterpreter/ && ~/Desktop/met.exe

where z is a shared folder pointing to my installation of Metasploit Framework on my host machine, and met.exe is a staged Windows payload.

Exploit output:

msf6 post(windows/gather/openssh_password_search) > time run pid=6460
