ice: fix retry for AQ command 0x06EE

Executing ethtool -m can fail reporting a netlink I/O error while firmware
link management holds the i2c bus used to communicate with the module.

According to Intel(R) Ethernet Controller E810 Datasheet Rev 2.8 [1]
Section 3.3.10.4 Read/Write SFF EEPROM (0x06EE)
request should to be retried upon receiving EBUSY from firmware.

Commit e9c9692c8a81 ("ice: Reimplement module reads used by ethtool")
implemented it only for part of ice_get_module_eeprom(), leaving all other
calls to ice_aq_sff_eeprom() vulnerable to returning early on getting
EBUSY without retrying.

Remove the retry loop from ice_get_module_eeprom() and add Admin Queue
(AQ) command with opcode 0x06EE to the list of commands that should be
retried on receiving EBUSY from firmware.
