server: fix issue while list ssh keypairs by keyword

[ustcweizhou]

Description

in 4.13, list sshkeypairs with keyword will ignore the search by name if name is specifed.
Fixes an issue in #3098

for example,

(local) > list sshkeypairs name=wei keyword=wei filter=name
{
  "count": 3,
  "sshkeypair": [
    {
      "name": "wei3"
    },
    {
      "name": "wei2"
    },
    {
      "name": "wei"
    }
  ]
}

with this patch ,it gives correct result.

(local) > list sshkeypairs name=wei keyword=wei filter=name
{
  "count": 1,
  "sshkeypair": [
    {
      "name": "wei"
    }
  ]
}
