user_ta: should go for other TA stores on any load error

There seems to be an issue that if RPMB_FS is enabled in
OPTEE and TA is present in REE (normal file system), if
priority for secure storage TA is higher and RPMB
initialization fails, the error is returned and the
OPTEE doesn't goes to find the TA from REE TA store.

The issue is fixed by adding a 'continue' statement after
printing the respective error.

core: define syscall_t as void (*)(void)

As such,

core: define syscall_t as void (*)(void)

syscall_t is currently typedef'ed as TEE_Result (*)(void). It is used to
represent a pointer to any system call, in the syscall table for instance.
As such, the exact type behind syscall_t cannot reflect all the syscalls
since they have different prototypes. The current declaration with a
TEE_Result return type was probably chosen because it was a common
characteristic of all syscalls to return a TEE_Result.

However, this type causes compilation warnings with GCC 8.1:

core/arch/arm/tee/arch_svc.c:43:36: warning: cast between incompatible function types from ‘void (*)(long unsigned int)’ to ‘TEE_Result (*)(void)’ {aka ‘unsigned int (*)(void)’} [-Wcast-function-type]
#define SYSCALL_ENTRY(_fn) { .fn = (syscall_t)_fn }
^
core/arch/arm/tee/arch_svc.c:50:2: note: in expansion of macro ‘SYSCALL_ENTRY’
SYSCALL_ENTRY(syscall_sys_return),
^~~~~~~~~~~~~

The solution is to use 'void (*)(void)' instead, as explained in the GCC
documentation:

-Wcast-function-type

Warn when a function pointer is cast to an incompatible function
pointer. [...] The function type void (*) (void) is special and matches
everything, which can be used to suppress this warning. [...]
