Arnd Bergmann 54233a4254 uretprobe: change syscall number, again
Despite multiple attempts to get the syscall number assignment right
for the newly added uretprobe syscall, we ended up with a bit of a mess:

 - The number is defined as 467 based on the assumption that the
   xattrat family of syscalls would use 463 through 466, but those
   did not make it into 6.11.

 - The include/uapi/asm-generic/unistd.h file still lists the number
   463, but the new scripts/syscall.tbl that was supposed to have the
   same data lists 467 instead as the number for arc, arm64, csky,
   hexagon, loongarch, nios2, openrisc and riscv. None of these
   architectures actually provide a uretprobe syscall.

 - All the other architectures (powerpc, arm, mips, ...) don't list
   this syscall at all.

There are two ways to make it consistent again: either list it with
the same syscall number on all architectures, or only list it on x86
but not in scripts/syscall.tbl and asm-generic/unistd.h.

Based on the most recent discussion, it seems like we won't need it
anywhere else, so just remove the inconsistent assignment and instead
move the x86 number to the next available one in the architecture
specific range, which is 335.
