regmap: Fix race condition in hwspinlock irqsave routine

In the Linux kernel, the following vulnerability has been resolved:

regmap: Fix race condition in hwspinlock irqsave routine

Previously, the address of the shared member '&map->spinlock_flags' was
passed directly to 'hwspin_lock_timeout_irqsave'. This creates a race
condition where multiple contexts contending for the lock could overwrite
the shared flags variable, potentially corrupting the state for the
current lock owner.

Fix this by using a local stack variable 'flags' to store the IRQ state
temporarily.
