Catalin Marinas 81fc03909a kmemcheck: Test the full object in kmemcheck_is_obj_initialized()
This is a fix for bug #14845 (bugzilla.kernel.org). The update_checksum()
function in mm/kmemleak.c calls kmemcheck_is_obj_initialised() before scanning
an object. When KMEMCHECK_PARTIAL_OK is enabled, this function returns true.
However, the crc32_le() reads smaller intervals (32-bit) for which
kmemleak_is_obj_initialised() may be false leading to a kmemcheck warning.

Note that kmemcheck_is_obj_initialized() is currently only used by
kmemleak before scanning a memory location.
