sata_promise: other cleanups
Minor coding-style fixes for sata_promise:
- remove stray blank lines
- fix checkpatch.pl errors; warnings about long lines
remain, but I don't intend to address those at this time
- remove two inline directives: neither is essential and
both functions are trivially inlinable anyway by virtue
of being static and having a single unique call site
- fix comment in pdc_interrupt(): the bits in PDC_INT_SEQMASK
denote SEQIDs not tags, the distinction becomes important
when NCQ gets implemented
