[PATCH] zsmalloc: avoid unused-function warning

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

obj_allocated() can be called from two places that are each
inside of an #ifdef. When both are disabled, the compiler warns:

mm/zsmalloc.c:900:13: error: 'obj_allocated' defined but not used [-Werror=unused-function]

Rather than trying to figure out the correct #ifdef, mark the
trivial function as 'inline', which implies __maybe_unused and
shuts up the warning.

Fixes: 796c71ac728e ("zsmalloc: fix a race with deferred_handles storing")
