Fix modpost Section mismatch error in i915_globals_exit().
Since both an __init function and an __exit function can call
i915_globals_exit(), any function that i915_globals_exit() calls
should not be marked as __init or __exit. I.e., it needs to be
available for either of them.

WARNING: modpost: vmlinux.o(.text+0x8b796a): Section mismatch in reference from the function i915_globals_exit() to the function .exit.text:__i915_globals_flush()
The function i915_globals_exit() references a function in an exit section.
Often the function __i915_globals_flush() has valid usage outside the exit section
and the fix is to remove the __exit annotation of __i915_globals_flush.

ERROR: modpost: Section mismatches detected.
Set CONFIG_SECTION_MISMATCH_WARN_ONLY=y to allow them.
