ath9k: htc: clean up statistics macros

[ Upstream commit d7fc76039b74ad37b7056d5607b05d7cb31a5404 ]

I've changed *STAT_* macros a bit in previous patch and I seems like
they become really unreadable. Align these macros definitions to make
code cleaner and fix folllowing checkpatch warning

ERROR: Macros with complex values should be enclosed in parentheses

Also, statistics macros now accept an hif_dev as argument, since
macros that depend on having a local variable with a magic name
don't abide by the coding style.

No functional change
