drm/xe/guc: Bump the G2H queue size to account for page faults

With the increase in the size of the recoverable page fault
queue, we want to ensure the initial messages from GuC in
the G2H buffer have space while we transfer those out to the
actual pf_queue. Bump the G2H queue size to account for this
increase in the pf_queue size.
