[v2 PATCH] crypto: caam/qi* - Use cpumask_var_t instead of cpumask_t

[Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx>]

Switch cpumask_t to cpumask_var_t as the former may be too big
for the stack:

  CC [M]  drivers/crypto/caam/qi.o
  CC [M]  drivers/crypto/caam/caamalg_qi2.o
../drivers/crypto/caam/qi.c: In function ‘caam_qi_init’:
../drivers/crypto/caam/qi.c:808:1: warning: the frame size of 1056 bytes is larger than 1024 bytes [-Wframe-larger-than=]
  808 | }
      | ^
  CHECK   ../drivers/crypto/caam/qi.c
../drivers/crypto/caam/caamalg_qi2.c: In function ‘dpaa2_dpseci_setup’:
../drivers/crypto/caam/caamalg_qi2.c:5135:1: warning: the frame size of 1032 bytes is larger than 1024 bytes [-Wframe-larger-than=]
 5135 | }
      | ^

Also fix the error path handling in qi.c.
