Bart Van Assche 7725c45682 ata: libata: Document when host->eh_mutex should be held ...

Annotate the following functions with __must_hold(&host->eh_mutex):
 * All ata_port_operations.error_handler() implementations.
 * ata_eh_reset() and ata_eh_recover() because these functions call
   ata_eh_release() and ata_eh_acquire().
 * All callers of ata_eh_reset() and ata_eh_recover().

Enable Clang's context analysis. This will cause the build to fail if
e.g. a locking bug would be introduced in an error path. This patch
should not affect the generated assembler code.
