net: phy: micrel: Fix error handling

Fix the following error, the $ret variable handling must
be part of the loop, while due to the missing parenthesis
it was not.

drivers/net/phy/micrel.c: In function ‘ksz9021_of_config’:
drivers/net/phy/micrel.c:303:2: warning: this ‘for’ clause does not guard... [-Wmisleading-indentation]
  for (i = 0; i < ARRAY_SIZE(ofcfg); i++)
  ^~~
drivers/net/phy/micrel.c:305:3: note: ...this statement, but the latter is misleadingly indented as if it is guarded by the ‘for’
   if (ret)
