gpu: nvgpu: fix CERT-C EXP40-C issue in posix utils

Browse Source 
Remove const from __mptr declaration to fix EXP40-C violation.

cert_exp40_c_violation: Casting pointer "__mptr" with type
 "struct nvgpu_clk_dev const *" to type "char *" allows an
 object defined with a const-qualified type to be modified
 through use of an lvalue with non-const-qualified type

Considering implementation of container_of() a const is
not required.
