e1000e: cleanup: rename goto labels to be more meaningful

In the following functions, rename the generic 'out' goto label to the more
descriptive 'release' to indicate the type of common work that is done
before exiting the functions.  No functional change, cosmetic only.

e1000_sw_lcd_config_ich8lan()
e1000_oem_bits_config_ich8lan()
e1000_init_phy_wakeup()
e1000e_write_phy_reg_bm()
e1000e_read_phy_reg_bm()
e1000e_read_phy_reg_bm2()
