s390/dasd: Add __context_unsafe() attribute to various functions

Browse source

Disable context analysis for various functions to get rid of context
analysis compile time warnings using clang caused by conditional
locking like e.g.:

drivers/s390/block/dasd_eckd.c:1462:3:
  warning: releasing mutex 'dasd_pe_handler_mutex' that was not held [-Wthread-safety-analysis]
 1462 |                 mutex_unlock(&dasd_pe_handler_mutex);
      |                 ^

Use __context_unsafe() to provide a short comment why context analysis is
disabled for each function. It doesn't look like those functions can be
easily reworked to get rid of conditional locking.
Therefore disable context analysis for (only) those functions.
