Fix: SMB servers load problem

#12704
I'm not pro in c_sh,
This is only a temporary solution.
Because my work relies heavily on various mapped network drives,
Till now, this patch work for me.

Steps used to test these changes

1） Enter an smb that has been mapped as a network drive like "Y:\Download"
2）enter the directory containing a large number of large compressed files and wait for them to be lod.
3) Observe whether the loading speed is the same with "\192.168.0.1\nfs\Download"

ps:
The root cause may be the reading of the zip file，
Although it has not been tested, this is just a guess. Will huge files on slow devices have similar phenomena?
I also think that the compressed file recognition problem I mentioned in #12704 may aggravate this phenomenon.
Additionally, I would suggest that the file system type detection could be more unified into one function, rather than being everywhere.
