LU-18468 tests: write PAGE_SIZE for sanity-flr/211

Do not write smaller than PAGE_SIZE (=64KiB on aarch64/ppc64) when
using "dd oflag=direct" for sanity-flr test_211.  Otherwise, this
will fail on clients/servers that do not support unaligned direct IO.

Test-Parameters: trivial
Test-Parameters: testlist=sanity-flr env=ONLY=211 clientarch=aarch64 clientdistro=el9.3 serverversion=2.14
Fixes: b5db891cad ("LU-18468 llapi: always truncate mirrors on resync")
