drm/xe: Fix lockdep warning in xe_force_wake calls

Use spin_lock_irqsave, spin_unlock_irqrestore

Fix for below:
[13994.811263] ========================================================
[13994.811295] WARNING: possible irq lock inversion dependency detected
[13994.811326] 6.6.0-rc3-xe #2 Tainted: G     U
[13994.811358] --------------------------------------------------------
[13994.811388] swapper/0/0 just changed the state of lock:
[13994.811416] ffff895c7e044db8 (&cpuctx_lock){-...}-{2:2}, at:
__perf_event_read+0xb7/0x3a0
[13994.811494] but this lock took another, HARDIRQ-unsafe lock in the
past:
[13994.811528]  (&fw->lock){+.+.}-{2:2}
[13994.811544]

               and interrupts could create inverse lock ordering between
them.

               other info that might help us debug this:
[13994.811636]  Possible interrupt unsafe locking scenario:

                *** DEADLOCK ***

v2: Use spin_lock in atomic context and spin_lock_irq in a non atomic
context (Matthew Brost)

v3: just use spin_lock_irqsave/restore
