Subject: [PATCH stable 6.1] scripts/gdb: fix SB_* constants parsing

commit 6a59cb5158bff13b80f116305155fbe4967a5010 upstrean

--0000000000009a0c9905fd9173ad
Content-Transfer-Encoding: 8bit

After f15afbd34d8f ("fs: fix undefined behavior in bit shift for
SB_NOUSER") the constants were changed from plain integers which
LX_VALUE() can parse to constants using the BIT() macro which causes the
following:

Reading symbols from build/linux-custom/vmlinux...done.
Traceback (most recent call last):
  File "/home/fainelli/work/buildroot/output/arm64/build/linux-custom/vmlinux-gdb.py", line 25, in <module>
    import linux.constants
  File "/home/fainelli/work/buildroot/output/arm64/build/linux-custom/scripts/gdb/linux/constants.py", line 5
    LX_SB_RDONLY = ((((1UL))) << (0))

Use LX_GDBPARSED() which does not suffer from that issue.

Fixes: f15afbd34d8f ("fs: fix undefined behavior in bit shift for SB_NOUSER")
