scsi: ufs: qcom: Remove the MSI descriptor abuse

Browse source

The driver abuses the MSI descriptors for internal purposes. Aside of core
code and MSI providers nothing has to care about their existence. They have
been encapsulated with a lot of effort because this kind of abuse caused
all sorts of issues including a maintainability nightmare.

Rewrite the code so it uses dedicated storage to hand the required
information to the interrupt handler and use a custom cleanup function to
simplify the error path.

No functional change intended.
