[PATCH]crypto:hifn_795x.c Fix warning: variable 'ctx' set but not used

[Justin P. Mattock]

The below fixes a warning message generated by GCC
  CC [M]  drivers/crypto/hifn_795x.o
drivers/crypto/hifn_795x.c: In function 'hifn_flush':
drivers/crypto/hifn_795x.c:2021:23: warning: variable 'ctx' set but not used
drivers/crypto/hifn_795x.c: In function 'hifn_process_queue':
drivers/crypto/hifn_795x.c:2142:23: warning: variable 'ctx' set but not used

Please have a look, and let me know if this is legit or not.
