soc/amd/common/block/psp: fix logic bug in psp_get_* functions
The functions psp_get_ftpm_capabilties, psp_get_hsti_state, and
psp_get_psp_capabilities which were added in commit 5e7ab1a23346
("soc/amd/common/psp: add helper functions to retrieve capability bits")
have a bug in the 'cmd_status' error handling logic. In case of an
error, 'cmd_status' is non-zero, while the check somehow expected the
opposite. Fix the bug by returning an error if 'cmd_status' is non-zero.
