selftests/intel_pstate: fix operand expected error 

mainline inclusion
from mainline-v6.12-rc6
commit 6553bfcb8499bf5e7e6d07d93f29459198dba798
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IB6W7T

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=6553bfcb8499bf5e7e6d07d93f29459198dba798

--------------------------------

Running "make kselftest TARGETS=intel_pstate" results in
the following errors:
- ./run.sh: line 90: / 1000: syntax error: operand expected
(error token is "/ 1000")
- ./run.sh: line 92: / 1000: syntax error: operand expected
(error token is "/ 1000")

This fix allows to have cross-platform compatibility when
using arithmetic expression with command substitutions.
