[PATCH] staging: r8188eu: remove unused variable and DBG_88E in hal/rtl8188e_cmd.c

[Phillip Potter <phil@philpotter.co.uk>]

Remove set but unused variable init_rate from rtl8188e_Add_RateATid
function in hal/rtl8188e_cmd.c, as it fixes a kernel test robot warning.
Removing the call to get_highest_rate_idx has no side effects here so is
safe.

Also remove the DBG_88E macro call in this function, as it is not
particularly clear in my opinion. Additionally, rename variable
shortGIrate to short_gi_rate to conform to kernel camel case rules,
and improve general spacing around operators, some of which triggers
checkpatch 'CHECK' messages. These are not related to the test robot
warning.
