add context cancellation to disk windows

[StefanoBalzarottiNozomi]

I readded context cancellation. context is cancelled as soon as possible, but there are no leaking goroutines, if a system call blocks, code returns as soon as the system call returns.

Sorry for late reponse. Great work on adding context cancellation! However, I noticed the context checking pattern is inconsistent across the loop implementations:

• processLogicalDrives (line 195): uses select statement
• processVolumeLoop (line 145): uses if ctx.Err() != nil
• processMountsForVolume (line 178): uses if ctx.Err() != nil

For consistency and following Go idioms, I'd recommend using select for all loop-based context checks. The select statement is the more conventional pattern when checking context cancellation in loops. How about to use select statement in processVolumeLoop and processMountsForVolume ?

Sorry for late reponse. Great work on adding context cancellation! However, I noticed the context checking pattern is inconsistent across the loop implementations:

* `processLogicalDrives` (line 195): uses `select` statement

* `processVolumeLoop` (line 145): uses `if ctx.Err() != nil`

* `processMountsForVolume` (line 178): uses `if ctx.Err() != nil`

For consistency and following Go idioms, I'd recommend using select for all loop-based context checks. The select statement is the more conventional pattern when checking context cancellation in loops. How about to use select statement in processVolumeLoop and processMountsForVolume ?

done, now loops uses select with context

Thank you for updating the PR. The context cancellation implementation looks good - it properly checks for cancellation at each loop iteration without leaking goroutines. LGTM!
