vdso/datapage: Use correct clock mode name in comment 

While the explanation for time namespace <-> vdso interactions is very
helpful it uses the wrong name in the comment when describing the clock
mode making grepping a bit annoying.

This seems like an accidental oversight when moving from VCLOCK_TIMENS
to VDSO_CLOCKMODE_TIMENS. It seems that
660fd04f93 ("lib/vdso: Prepare for time namespace support") misspelled
VCLOCK_TIMENS as VLOCK_TIMENS which explains why it got missed when
VCLOCK_TIMENS became VDSO_CLOCKMODE_TIMENS in
2d6b01bd88 ("lib/vdso: Move VCLOCK_TIMENS to vdso_clock_modes").

Update the comment to use VDSO_CLOCKMODE_TIMENS.

Fixes: 660fd04f93 ("lib/vdso: Prepare for time namespace support")
Fixes: 2d6b01bd88 ("lib/vdso: Move VCLOCK_TIMENS to vdso_clock_modes")
