The 'dso->kernel' condition is true also for kernel modules now,
and there are several places that were omited by the initial change:
- we need to identify modules separately in dso__process_kernel_symbol
- we need to set 'dso->kernel' for module from buildid table
- there's no need to use 'dso->kernel || kmodule' in one condition
Committer testing:
Before:
# perf test -v object
<SNIP>
Objdump command is: objdump -z -d --start-address=0xffffffff813e682f --stop-address=0xffffffff813e68af /usr/lib/debug/lib/modules/5.7.14-200.fc32.x86_64/vmlinux
Bytes read match those read by objdump
Reading object code for memory address: 0xffffffffc02dc257
File is: /lib/modules/5.7.14-200.fc32.x86_64/kernel/arch/x86/crypto/crc32c-intel.ko.xz
On file address is: 0xffffffffc02dc2e7
dso__data_read_offset failed

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
