net: smc911x: Adjust indentation in smc911x_phy_configure

commit 5c61e22 upstream.

Clang warns:

../drivers/net/ethernet/smsc/smc911x.c:939:3: warning: misleading
indentation; statement is not part of the previous 'if'
[-Wmisleading-indentation]
         if (!lp->ctl_rfduplx)
         ^
../drivers/net/ethernet/smsc/smc911x.c:936:2: note: previous statement
is here
        if (lp->ctl_rspeed != 100)
        ^
1 warning generated.

This warning occurs because there is a space after the tab on this line.
Remove it so that the indentation is consistent with the Linux kernel
coding style and clang no longer warns.
