Title:
  channel filters don't work wit PVA

Status in EPICS Base:
  Confirmed

Bug description:
  When using pvget with filters, only the number of elements is adjusted but not the data.
  It works with Channel Access.

  Example record:

  record (aai, "TEST") {
  field(FTVL, "SHORT")
  field(NELM, "10")
  field(INP, [9,8,7,6,5,4,3,2,1])
  field(PINI, "YES")
  info(test, "Hello World")
  }

  $ caget TEST TEST.{arr:{s:5}} TEST.{arr:{i:2}} 'TEST.{info:{n:"test"}}'
  TEST 10 9 8 7 6 5 4 3 2 1 0
  TEST.{arr:{s:5}} 5 4 3 2 1 0
  TEST.{arr:{i:2}} 5 9 7 5 3 1
  TEST.{info:{n:"test"}}         Hello World

  $ pvget TEST TEST.{arr:{s:5}} TEST.{arr:{i:2}} 'TEST.{info:{n:"test"}}'
  TEST                   2021-03-12 10:23:15.524  [9,8,7,6,5,4,3,2,1]
  TEST.{arr:{s:5}}       2021-03-12 10:23:15.524  [9,8,7,6,5]
  TEST.{arr:{i:2}}       2021-03-12 10:23:15.524  [9,8,7,6,5]
  TEST.{info:{n:"test"}} 2021-03-12 10:23:15.524  9
