Subject: [PATCH] arm64: compat: Fix syscall number of compat_clock_getres

The syscall number of compat_clock_getres was erroneously set to 247
instead of 264. This causes the vDSO fallback of clock_getres to land
on the wrong syscall.

Address the issue fixing the syscall number of compat_clock_getres.

Fixes: 53c489e1dfeb6 ("arm64: compat: Add missing syscall numbers")
