Staging: hv: blkvsc_drv: Cleanup spin lock usage

This spin lock is potentially acquired from interrupt context.
Ensure that the interrupts are blocked whenever the lock is held.
The current code was not consistent with regards to blocking
interrupts - the same lock would be acquired without blocking
interrupts in some instance while the interrupts would be blocked
in other instances. Fix this potential deadlock problem.
