libata: cleanup SAT error translation

- Remove duplicate Medium Error Entry.

- Fix translations to match SAT2 translation table.

- Remove warning messages when translation is not found when decoding
  error or status register.

- Goes through status register decoding when only ABRT bit is set in
  error register.

Tested: When a disk fails, it sets

  Status = 0x71 [DRDY DF ERR] , Error = 0x4 [ABRT]

This patch will make the sense key HARDWARE_ERROR instead.

When there is a simple command syntax error:

  Status = 0x51 [DRDY ERR] , Error = 0x4 [ABRT]

The sense key remains ABORTED_COMMAND.

tj: Some updates to the description and comments.
