[PATCH] stmmac: Remove spin_lock call in stmmac_get_pauseparam()

[Emil Goode <emilgoode@gmail.com>]

The following patch removed unnecessary spin_lock/unlock calls
in ethtool_ops callback functions. In the second and final version
of the patch one spin_lock call was left behind.

    net: driver: stmicro: Remove some useless the lock protection

This introduced the following sparse warning:

drivers/net/ethernet/stmicro/stmmac/stmmac_ethtool.c:424:1: warning:
	context imbalance in 'stmmac_get_pauseparam' -
	different lock contexts for basic block

Hello,

Some spin_lock/unlock calls where also left behind in
stmmac_ethtool_setsettings(), I'm not sure if it was intentional?

Best regards,

Emil Goode
