[PATCH] scripts/gdb: fix mount flags for lx-symbols

[PATCH] scripts/gdb: fix mount flags for lx-symbols

[Daniel Gomez]

From: Daniel Gomez <da.gomez@samsung.com>

mount flags have been converted to enum making lx-symbols not able to
find them when debugging. Use the appropriate LX_GDBPARSED macro for the
new enum.

Error:
Reading symbols from vmlinux...
Python Exception <class 'NameError'>: name 'MNT_NOSUID' is not defined

Fixes: 101f2bbab541 ("fs: convert mount flags to enum")

My patch is a duplicate of this:
https://lore.kernel.org/all/20250618134629.25700-2-johannes@sipsolutions.net/T/#u

Already in linux-next with commit id a333d056e276 ("scripts: gdb: move MNT_*
constants to gdb-parsed").

And here another duplicate:
https://lore.kernel.org/all/20250601055027.3661480-1-tony.ambardar@gmail.com/

Sorry for the confusion and extra noise.
